Chapter 17, Problem 42P
Interpretation Introduction

(a)

Interpretation:

The reaction of phenyl acetic acid with given reagents should be completed.

Concept Introduction:

Phenylacetic acid contains one −COOH group with molecular formula C6 H5 -CH2 -COOH. Carboxylic acids react with base to form salt and water. This reaction is called as neutralization reaction. The reduction of carboxylic acid form carbonyl compounds and alcohols whereas reaction with alcohol forms ester.

Answer to Problem 42P

C6H5-CH2-COOH +  NaOH C6H5-CH2-COO-Na+ + H2.

Explanation of Solution

The reaction of C6 H5 -CH2 -COOH with sodium hydroxide forms sodium salt of C6 H5 -CH2 -COOH with water. This is a neutralization reaction as carboxylic acid reacts with base to form salt.

Answer to Problem 42P

C6H5-CH2-COOH +  LiAlH4/ H2O C6H5-CH2-CH2-OH + LiOH + Al(OH)3.

Explanation of Solution

The reaction of C6 H5 -CH2 -COOH with lithium ammonium hydride followed by hydrolysis leads to formation of 2-phenylethanol. This is an example of reduction reaction and LiAlH4 is a reducing agent.

Interpretation Introduction

Answer to Problem 42P

C6 H5 -CH2 -COOH + NaBH4 / H2 O (No reaction.

Explanation of Solution

NaBH4 with water is a weak reducing agent therefore it cannot reduce the carboxylic acid and no reaction is observed with it.

Answer to Problem 42P

C6H5-CH2-COOH +  H2/ Ni  No reaction .

Explanation of Solution

H2 / Ni cannot reduce carboxylic acid group as it is reducing agent for alkene and alkyne to alkane. Hence no reaction will be observed here.
