Name the type of organic compound from the following description of its functional group:

(a) N-containing group with single and double bonds;

(b) the group that is not polar and has a double bond;

(c) the polar group that has a double bond and cannot be at the end of a C chain;

(d) the group that has only single bonds and is basic in water

A group having N (nitrogen) and having a double, as well as triple bond, is amide as a carbonyl group, so it contains a double bond and has an amine group attached with carbonyl carbon through the single bond as shown:

Amide

Non-polar is the group formed by the covalent bond. The electrons share the electrons and are equally shredded like an alkene that has a double bond between carbon. The electrons are similarly charged like each hydrogen chare one electron carbon.

Alkene

The polar group is the covalently bonded group formed by unequal sharing of electrons. The group that has double found and is never present at the end is a ketone that contains carbonyl and is always present between the alkyl groups.

Ketone

Ammonia is a group that has a single bond and is always basic in water because, in water, ammonia takes the hydrogen and form hydroxide ion and the ammonium ions and contain single bonds alloys as given:
