Joint Entrance Examination (JEE) is a common entrance examination conducted by CBSE for admissions invarious engineering colleges in India. Every student appearing for this examination aspires to score his best and join one of the prestigious universities in India. Chemistry is one of the most scoring subjects to enhance your rank in JEE. Questions from chemistry are relatively lesser time taking in comparison to maths and physics. Of all the topics in chemistry, “Alcohols and phenols” is one of the most important topics to cover. Some FAQ’s related to alcohols and phenols are explained below:
Question: What are some of the important topics to cover in “alcohol and phenols”?
Answer: Alcohols and phenols are basically hydrocarbons where one or more hydrogen atom is replaced with one or more hydroxyl group.If we go through the previous year JEE question papers we will find that almost every year at least two to three questions are asked from this chapter. Main concepts involved in this chapter include:
- acidity of alcohol and phenols
- solubility of alcohols in water
- boiling point of alcohols
- resonance in phenolic rings
- order of dehydration for primarysecondary and tertiary alcohols
- directive influence of hydroxyl functional group in phenols
Question: What are some of the important reactions of “alcohol and phenols”?
Answer: According to JEE syllabus, all the reactions involving preparation of phenols are very important, other important reactions include electrophilic aromatic substitution reaction of phenols like Kolbe’s reaction and Reimer Tiemann reaction, dehydration reaction of alcohol, oxidation of alcohol, etc.
Questions: Which reference books can one follow for “alcohol and phenols”?
Answer: While covering “alcohol and phenols” for JEE chemistry, one must go through the NCERT class 12thchemistry textbook part-2. A brisk walk through this chapter from NCERT not only gives you a sound idea of the various topics you need to cover according to the JEE syllabus but also develops the fundamentals regarding the chapter. Apart from this you can follow a reference book to understand mechanisms of reactions not given in the NCERT textbook. Some authentic books for understanding the mechanism of organic reactions include books from authors likeSolomons & Fryhle, Morrison Boyd, etc. Once you have developed concepts on this topic, you can practice questions on this topic from the books of authors like “M.S. Chauhan”, etc.
