in the neet exam there is a section of chemistry which consists of 180 marks. Class 12 chemistry part 2 is very important for neet and has a good weightage in the paper. Questions from alcohols, carboxylic acids, bio molecules are  asked frequently in previous years. Important reactions of carboxylic acids, aldehyde, alcohols and carbon containing nitrogen is asked. Incomplete reactions are given in the question paper and you have to complete it. Also, you are given few reactants and you have to tell the product using a reaction. Such questions are easy and they require concentration and a good knowledge of reactions and the conditions required for getting a product.

I will suggest you to read all the important reactions and write it on a paper. Revise these reactions daily. Solve previous years chemistry section to make your preparation better and it also helps in identifying the weak areas where you need to work.
