The boiling points of the following hydrides follow the order of
1 \(N{H_3} > As{H_3} > P{H_3} > Sb{H_3}\)
2 \(Sb{H_3} > As{H_3} > P{H_3} > N{H_3}\)
3 \(Sb{H_3} > N{H_3} > As{H_3} > P{H_3}\)
4 \(N{H_3} > P{H_3} > As{H_3} > Sb{H_3}\)
Explanation:
(c) Boiling points of \(Sb{H_3}(254\;K),\;N{H_3}(238\;K)\), \(As{H_3}(211\;K)\) and \(P{H_3}\;(185\;K)\) therefore boiling points are of the order \(Sb{H_3} > N{H_3} > As{H_3} > P{H_3}\).
