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.
