Chapter 22.7, Problem 10P

Interpretation Introduction

a)

Interpretation:

The most acidic hydrogen in molecule CH₃CH₂CHO is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To give the most acidic hydrogen in molecule of CH₃CH₂CHO.

Interpretation Introduction

b)

Interpretation:

The most acidic hydrogen in molecule (CH₃)₃CCOCH is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To give the most acidic hydrogen in molecule of (CH₃)₃CCOCH.

Interpretation Introduction

c)

Interpretation:

The most acidic hydrogen in molecule CH₃CO₂H is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To give the most acidic hydrogen in molecule of CH₃CO₂H.

Interpretation Introduction

d)

Interpretation:

The most acidic hydrogen in Benzamide is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To give the most acidic hydrogen in Benzamide.

Interpretation Introduction

e)

Interpretation:

The most acidic hydrogen in a molecule CH₃CH₂CH₂CN is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To identify the most acidic hydrogen in a molecule CH₃CH₂CH₂CN.

Interpretation Introduction

f)

Interpretation:

The most acidic hydrogen in a molecule CH₃CON(CH₃)₂ is to be given.

Concept introduction:

Hydrogen’s on carbon next to a carbonyl group are acidic. In general, α β dicarbonyl compounds is most acidic, a ketone or aldehyde is next acidic and a carboxylic acid derivative is least acidic. Alcohols, phenols and carboxylic acid are also acidic because of their –OH hydrogen’s.

To give:

To identify the most acidic hydrogen in a molecule CH₃CON(CH₃)₂.
