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

Respuesta :

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

Explanation:

  • For 1: [tex]NH_3[/tex]

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:  [tex]NRH_2[/tex]

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:  [tex]R_2NH[/tex]

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:  [tex]R_3N[/tex]

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:  [tex]R^-[/tex]

The given group is known as alkyl group such as methyl [tex](CH_3^-)[/tex], ethyl [tex](C_2H_5^-)[/tex] etc..

Hence, the correct answer is alkyl group.

  • For 6:  [tex]NH_4^+[/tex]

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

Hence, the correct answer is ammonium ion.
