Concept explainers
(a)
Interpretation:
The number of aldehyde groups and ketone groups present in progesterone has to be given.
Concept Introduction:
Carbonyl groups are the one which contain a double bond between carbon and oxygen atom.
The groups that is attached to the carbonyl carbon atom can be either hydrogen or carbon atom. If the attached atoms are hydrogen and a carbon atom means then the compound is an aldehyde and if they are two carbon atoms means then the compound is a ketone.
(b)
Interpretation:
The number of aldehyde groups and ketone groups present in 2-heptanone has to be given.
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,
The groups that is attached to the carbonyl carbon atom can be either hydrogen or carbon atom. If the attached atoms are hydrogen and a carbon atom means then the compound is an aldehyde and if they are two carbon atoms means then the compound is a ketone.
(c)
Interpretation:
The number of aldehyde groups and ketone groups present in dihydroxyacetone has to be given.
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,
The groups that is attached to the carbonyl carbon atom can be either hydrogen or carbon atom. If the attached atoms are hydrogen and a carbon atom means then the compound is an aldehyde and if they are two carbon atoms means then the compound is a ketone.
(d)
Interpretation:
The number of aldehyde groups and ketone groups present in cinnamaldehyde has to be given.
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,
