Hybridised state of bromine in bromine pentafluoride is

• A

  $s p^{3} d$
• B

  $d^{2} s p^{3}$
• C

  $d s p^{3}$
• Correct answer
  D

  $s p^{3} d^{2}$

Solution

Hybridisation = number of $\sigma$ bond $+$ lone pair $+$ coordinate bond $$ =5+1+0=6\left(s p^{3} d^{2}\right) $$

Hence, the correct answer is option: 'D'.
