Question

Can someone help me please?

Match these items.

1. NH3
alkyl group
2. NRH2
tertiary amine
3. R2NH
ammonia
4. R3N
ammonium ion
5. R-
secondary amine
6. NH4+
primary amine

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

Step-by-step 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.
