Question

Can someone help me please?

Answer 1

Nh3 is ammonia. Nh4+ is ammonium ion. NRH2 is primary amine, R2NH is secondary amine, R3N is tetiary amine. R is alkyl group

Answer 2

Explanation:

• For 1: $NH_3$

The given compound is formed from the combination of hydrogen and nitrogen. It is a colorless gas having a pungent smell.

Hence, the correct answer is ammonia.

• For 2:  $NRH_2$

The given functional group is known as amine. Two places of nitrogen are occupied by hydrogen and one by alkyl group, thus is considered as a primary amine.

Hence, the correct answer is primary amine.

• For 3:  $R_2NH$

The given functional group is known as amine. Two places of nitrogen are occupied by alkyl group one by hydrogen, thus is considered as a secondary amine.

Hence, the correct answer is secondary amine.

• For 4:  $R_3N$

The given functional group is known as amine. All the three places are occupied by alkyl group, thus is considered as a tertiary amine.

Hence, the correct answer is tertiary amine.

• For 5:  $R^-$

The given group is known as alkyl group such as methyl $(CH_3^-)$, ethyl $(C_2H_5^-)$ etc..

Hence, the correct answer is alkyl group.

• For 6:  $NH_4^+$

All the four places of nitrogen is occupied by hydrogen and it is known as ammonium ion.

Hence, the correct answer is ammonium ion.
