Question

Azane is IUPAC name of:
(A) Carbon dioxide
(B) Ammonia
(C) Quick lime
(D) ${H_2}S{O_4}$

Answer 1

Hint: ‘azo’ word is used for the compounds which contain nitrogen atoms. Azane does not contain double or triple bonds between the atoms. Azane contains a total of four atoms in its structure. It is basic in nature.

Complete Step-by-Step Solution:
We will get some information about azane.
- From the name azane, we can predict that the compound should contain nitrogen atoms. This is because the word ‘azo’ word is usually used to indicate the presence of nitrogen atoms in the compound.
- Out of the given compounds, carbon dioxide, ${H_2}S{O_4}$ and quicklime does not have nitrogen atoms in their structure. Ammonia contains nitrogen atoms and its molecular formula is $N{H_3}$.
- All azanes are acyclic and saturated hydro nitrogen compounds. So, all azanes contain only nitrogen and hydrogen atoms and they contain only single bonds.
- The general chemical formula of azanes is ${N_n}{H_{n + 2}}$ . So, they are homologous series of compounds.
- The simplest azane is ammonia and its molecular formula is $N{H_3}$. It is also known as Azane.
- The hydro nitrogen compounds can be divided into three broad categories namely linear, branched and cyclic compounds. The hydro nitrogen compounds may show isomerism. They can show structural isomerism.
- Thus, we can conclude that ammonia has IUPAC name Azane.

Therefore, the correct answer of the question is (B) ammonia.

Note: Remember that azanes is the collective name used for all the hydro nitrogen compounds which do not have any atom other than nitrogen and hydrogen and contain only single bonds. Azane name is used for ammonia only.
