Question

Molecular hydrides of formed from ______________

(a) f-block elements

(b) p- block elements

(c) d-block elements

(d) s- block elements

I got this question in my homework.

My enquiry is from Hydrogen topic in chapter Hydrogen of Chemistry – Class 11

Answer 1

The correct answer is (b) p- block elements

The explanation is: Molecular hydrides are also called as covalent hydrides and they are formed by elements of p-block those having higher electronegativity than hydrogen. They are again divided into electron deficient hydrides, electron precise hydrides and electron rich hydrides.
