Alcohols, Phenols and Ethers  

What is Alcohols, Phenols and Ethers

ALCOHOLS PHENOLS AND ETHERS

Introduction

This chapter is one of the most important chapters of the complete chemistry syllabus. Alcohols, phenols and ethers are formed by replacing one or more hydrogen atom by a hydroxyl group(OH) and an alkoxy group(R-O), respectively. These are a very important class of compounds that we see around us every time and use in our daily life. 

  • Alcohols are used to make wine and beer.
  • Ethanol burns as a fuel to form carbon dioxide and water. Using ethanol as a fuel has an advantage of less pollution.
  • Ethanol also used as an organic solvent to dissolve the organic compounds that are not dissolved in water.
  • Diethyl ether is used as a solvent in the laboratory.
  • Ether is also used as a refrigerant as it produces colling on evaporation.

How to prepare for Organic compounds containing oxygen?

  • This chapter is the part of organic chemistry. It is completely theory based. You are not supposed to memorize any formula and numerical practice for getting the good hold on this chapter. All you just need to remember is reaction mechanisms and important reactions.

  • For this chapter, first you must have your basic concepts completely clear that you can learn from the "Some basic principles of Organic Chemistry". For this, you must go through Unit 12 of the NCERT book 11th class part II thoroughly.

  • In the nutshell, it can be said that although this chapter is lengthier than other chapters but, it is a very simple and straightforward one. So always say a "Big YES" to this chapter.

Prescribed Books
For this chapter, first, the NCERT book is best for initial level preparation as well as for board exams. Now, after this, if you want to prepare for competitive exams like JEE and NEET, then these are the best books for you - O.P Tandon and R.K Gupta by Arihant publication. Meanwhile, in the preparation, you must continuously give the mock tests for the depth of knowledge. Our platform will help you to provide with the variety of questions for deeper knowledge with the help of videos, articles and mock tests.
