Answer 1

Answer:

group of atoms responsible for the characteristic reactions of a particular compound.

Explanation:

functional group is responsible for the characteristic property or behavior of a class of compounds. For example, hydroxyl ( –OH) group in alcohols. Examples of functional groups are: Hydroxyl group ( –OH), Aldehyde group ( –CHO), Ketone group ( carboxyic group ( –COOH).

Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.

Answer 2

1 ) Functional groups are the atoms or group of atoms attached to a hydrocarbon chain which changes the property of parent hydroarbon chain .

2) A functional group is responsible for the characteristic property or behavior of a class of compounds. For example, hydroxyl ( –OH) group in alcohols. Examples of functional groups are: Hydroxyl group ( –OH), Aldehyde group ( –CHO), Ketone group ( –CO) and carboxylic group ( –COOH).

3) Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde.
