MHT CET 2026 Chemistry question

Identify the number of lone pair and bond pair electrons present in the valence shell of central atom in .

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

Answer: (C)

Solution

Central atom Br (group 17) has 7 valence electrons. Three of them pair up with one electron each from three F atoms, forming 3 Br-F bond pairs. The remaining electrons form 2 lone pairs. So the valence shell of Br holds 3 bond pairs and 2 lone
