IGCSE Organic Chemistry notes

Which process causes the greatest increase in the distance between particles? A condensation B freezing C melting D sublimation 9. A student put There are two papers for each tier of entry - Foundation and Higher.

Each paper is split into two sections, Section A and Section B. The short answer questions contain different styles, including:. Multiple choice questions appear in both exam papers, and at both Tiers.

You have four options to choose from in a multiple choice question. You must only choose one of these options, by writing your answer A, B, C, or D in a box. Look at the displayed formula of an organic compound.

What is the name of this compound? A ethanoic acid. B ethanol.

14.1 Organic Chemistry & Fuels

C propanoic acid. D propanol. C [1]. DNA is a condensation polymer made from monomers called nucleotides. How many different nucleotides are used to make DNA molecules? A condensation polymer is made from two monomers. One of the monomers has two -COOH groups in its molecules. The other monomer has two -NH2 groups in its molecules.

Which one of the following is the polymer? A DNA. B polyester. C polyamide.Highly recommended by Loay Tamer Dr. Nervana is highly recommended for Chemistry class tuition, she knows how to deliver the information, make sure you understood it and able to apply it, also she puts a lot of effort on the practice before the exam to make sure you are ready for any level of questions Words can't explain by Omneya I have no enough words to explain how much I was lucky to be your studentyou were so patient and made chemistry like a piece of cake for usyour classes were so much fun yet challenging.

I wish those days come back by Heba Saeed I knew my respected instructor Dr. Nervana in At that time, I was unable to understand the chemistry very well. I faced difficulty with chemistry until I met Dr. She made a great effort to support me and my peers. I still remember when she used to stay awake till the mid of the night teaching me and my colleagues.

And with all of this huge effortshe was always smiling and willing to clear all of our doubts. I never hesitate to ask her any question at anytime because I always believe that she enjoys to support all of her students. Because of her, I scored excellent in chemistry IG. It's my pleasure to be Dr. Nervana's student. It was enjoyable by Alaa Hussain I enjoyed the environment overall. Best Teacher! Summary of solids liquids gases in the syllabus.

This blog only covers the organic chemistry topics which are included on the IGCSE chemistry syllabus. No more, no less. All of them aced in organic chemistry. I have explained everything to the point and in an easy to understand way, no-nonsense. After you finish this, you will definitely be more confident with organic chemistry.

Organic Chemistry is the study of compounds based on hydrocarbons and their derivatives. We will discuss their general formula, physical and chemical properties. I have covered all the organic chemistry basics with a complete breakdown. Please keep on reading and enjoy! We are going to learn about four main homologous series; they are Alkane, Alkene, Alcohol and carboxylic acid.

Organic Chemistry is a very tricky topic. The Homologous series is a family or group of hydrocarbons or derivatives having the same functional group, same general formula and similar chemical properties.

They also have a similar trend in physical properties. The functional group is simply an atom or group of atoms attached to the organic compound which dictates its chemical property. Gives its own chemical property. Also in some cases, it gives rise to some unique physical properties too. Do not worry if you are still confused about what a functional group is. I have explained this concept with some examples in this blog, that will make everything clear.

The General Formula is the formula to find out the molecular formula for an organic compound which is in a certain homologous series. The general formula of a homologous series gives the formula which shows how many hydrogen or another kind of atoms will be there for a given number of carbon atoms. This is how easily we use the general formula to easily determine how many atom s of each element are present.

This concept will become clear as you keep reading this blog. Alkane is the simplest of all the homologous series. It only has simple C-H bonds throughout its whole structure.

It does not have any functional group, hence alkanes are quite inert in nature. For example, Butane is an alkane with four carbon atoms. We can use the general formula of alkane to easily figure out its molecular formula. Similarly to Alkanes, alkenes also contains C-H bonds. The functional group of alkenes gives it some unique chemical properties. I will discuss that later on this blog with more details.

For example, butene is an alkene with four carbon atoms. We can easily use the general formula of alkene to determine the molecular formula of butene. In Alcohol, there is also C-H bonds present. Similar to alkanes and alkenes, we can also use the general formula to determine the molecular formula of specific alcohols. For example butanol is an alcohol with four carbon atoms. For a more advanced blog post on alcohol, please view this blog. General Formula C n H 2n O 2.

For Example: butanoic acid, a carboxlylic acid with four carbon atoms.Multiple choice questions appear throughout both exam papers, and at both Foundation tier and Higher tier. Multiple choice questions are usually asked as questions, often starting with 'What is? You have three or four options to choose from in a multiple choice question. You must choose the number of options asked for in the question by placing ticks in boxes.

Most multiple choice questions require just one tick, but a few ask for two ticks. You will not get a mark if you leave all the boxes blank, or if you put a tick in more than the required number of boxes. Multiple choice questions often have two answers that could, at first glance, be correct.

It is important to check all the answers before deciding which box to tick. It is also important to check that your chosen statement answers the question - some questions might include an option that is a correct statement, but that does not answer the question.

The apparatus in the diagram is used to separate a mixture of liquids in a fuel. What is apparatus W in the diagram? Tick one box. What is the name of this method of separation? This question has been written by a Bitesize consultant as a suggestion to the type of question that may appear in an exam paper.

What type of reaction is cracking? Which of the following is an alkane? Organic chemistry - Multiple choice questions Multiple choice questions appear throughout both exam papers, and at both Foundation tier and Higher tier. Sample question 1 - Foundation Question The apparatus in the diagram is used to separate a mixture of liquids in a fuel.
