(a)
Interpretation:
The number of aldehyde groups and ketone groups present in vanillin 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 carvone 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 cortisone 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)

Oil-based paints are often made with triglycerides. The colors or pigments often contain metal salts. Soap 'blooms' sometimes appear in old Renaissance paintings in museums leading to degradation of the artwork. How do these soap blooms form? Renaissance painters often washed their brushes with soap and water. The metals can catalyze the formation of triglycerides from fatty acids and glycerine in the paint. The metals can catalyze the hydrolysis of the triglycerides in the paint with water from the air. The soap used on the floors by the museum cleaning crew bonds to the surface of the painting.arrow_forward
