MHT CET 2026 Chemistry question

What is the number of bond pair of electrons and lone pair of electrons present in the valence shell of chalcogens in their hydride?

(A)2 - Bond pair and 1- lone pair of electrons
(B)2 - Bond pair and 2- lone pair of electronsCorrect
(C)3 - Bond pair and 1- lone pair of electrons
(D)3 - Bond pair and 2- lone pair of electrons

Answer: (B)

Solution

Chalcogens (group 16: O, S, Se, Te, Po) have six valence electrons (). Their hydrides have the formula (, , etc.). The central atom forms two single bonds with two H atoms, using two electrons (2 bond pairs), and the remaining four
