JEE Main Chemistry question
The sum of the number of lone pairs of electrons on each central atom in the following species is and (atomic numbers: N=7, F=9, S=16, Br=35, Te=52, Xe=54) **[JEE Advanced 2017]**
Answer: 4
Solution
: Te has 6 bond pairs + 1 lone pair (, pentagonal... actually distorted octahedral with 1 lone pair) = 1 lone pair. : Br has 2 bond pairs + 2 lone pairs (, bent) = 2 lone pairs.
