MHT CET 2025 Chemistry question

Identify a molecule having highest number of lone pair of electrons in valence shell of central atom

(A)
(B)
(C)Correct
(D)

Answer: (C)

Solution

Count lone pairs on the central atom as (valence electrons - electrons used in bonding)/2. : N has 5 valence electrons, uses 3 in N-H bonds, so 1 lone pair. : S has 6, uses 4, so 1 lone pair (see-saw shape).
