Chapter 20, Problem 20.20P

Interpretation Introduction

(a)

Interpretation:

The structure of the compound with molecular formula, ${\text{C}}_{\text{8}}{\text{H}}_{\text{6}}{\text{O}}_{\text{3}}$, which on reduction with ${\text{LiAlH}}_4$ give $1,4-\text{phenylenedimethanol}$ is to be stated.

Concept introduction:

The substances which on addition removes oxygen atom or hydrogen atom from the other substance, that is, reduces the other substances are known as reducing agents. Reducing agents themselves get oxidized. Strong reducing agents like ${\text{LiAlH}}_4$, reduces all the carbonyl groups present in a compound into alcohol.

Concept introduction:

The substances which on addition removes oxygen atom or hydrogen atom from the other substance, that is, reduces the other substances are known as reducing agents. Reducing agents themselves get oxidized. Strong reducing agents like ${\text{LiAlH}}_4$, reduces all the carbonyl groups and double bonds present in a compound into alcohol and single bonds respectively..
