A group 15 element forms dπ–dπ bond with transition metals. It also forms hydride,

Question

A group 15 element forms \(\mathrm{d} \pi-\mathrm{d} \pi\) bond with transition metals. It also forms hydride, which is a strongest base among the hydrides of other group members that form \(\mathrm{d} \pi-\mathrm{d} \pi\) bond. The atomic number of the element is ____ .

Answer 1

Answer is : 15

Phosphorus belongs to \(15^{\text {th }}\)group and forms \(\mathrm{d} \pi-\mathrm{d} \pi\) bond with transition metal and \(\mathrm{PH}_{3}\) is strongest base among the other group members excepet \(\mathrm{NH}_{3}\).
