Chapter 15, Problem 15.13EP

(a)

Interpretation Introduction

Interpretation:

Condensed structural formula for ${\text{C}}_{\text{1}}$ aldehyde has to be drawn and if the structure is not possible, this has to be indicated.

Concept Introduction:

Carbonyl groups are the one which contain a double bond between carbon and oxygen atom.  Aldehydes and ketones possess this carbonyl functional group in it.  The structural representation of a carbonyl group can be given as shown below,

An aldehyde is a carbonyl compound in which the carbonyl carbon atom is bonded to at least one hydrogen atom directly.  The other group attached to the carbonyl carbon atom can be alkyl, cycloalkyl, or aryl group.

A ketone is a carbonyl compound in which the carbonyl carbon atom is bonded to two other carbon atoms directly.  The groups attached to the carbonyl carbon atom can be alkyl, cycloalkyl, or aryl group.

(b)

Interpretation Introduction

Interpretation:

Condensed structural formula for ${\text{C}}_{\text{2}}$ ketone has to be drawn and if the structure is not possible, this has to be indicated.

(c)

Interpretation Introduction
