Embibe Experts Solutions for Chapter: Alcohols, Phenols and Ethers, Exercise 1: AP EAPCET 2020 (24-Sep Shift-1)

Arrange the following alcohols in order of their increasing boiling points.

Pentan-$1$-ol                     Butan-$2$-ol         Butan-$1$ol             Propane-$1$-ol                Ethanol

       I                                       II                        III                           IV                                 V

Identify $\mathrm{X}$ and $\mathrm{Y}$ in the following reactions

$\mathrm{R}-\mathrm{CH}=\mathrm{CH}-{\mathrm{CH}}_2\mathrm{OH}\stackrel{\mathrm{X}}{\to }\mathrm{R}-\mathrm{CH}=\mathrm{CH}-\mathrm{CHO}$
$\mathrm{R}-{\mathrm{CH}}_2\mathrm{OH}\stackrel{\mathrm{Y}}{⟶}\mathrm{R}-\mathrm{COOH}$

Identify the substrate in this reaction:

Identify $\mathrm{X}$ in the following reaction.

Assertion$\left(\mathrm{A}\right):-\mathrm{OH}$ group of phenol is ortho, para directing in electrophilic substitutions

Reason $\left(\mathrm{R}\right):-\mathrm{OH}$ group stabilises the arenium ion formed by the ortho, para attack of the electrophile

The correct answer is

Benzoic acid gives benzene on being heated with $\text{'}\mathrm{X}\text{'}$ and phenol gives benzene on being heated with $\text{'}\mathrm{Y}\text{'}.$ Then. $\mathrm{X}$ and $\mathrm{Y}$ respectively are:

The major product of the following reaction sequence is _______

Identify the product of the following reaction.
