Equilibrium Ques 55
55. Among boron trifluoride, stannic chloride and stannous chloride, Lewis acid is represented by
[1999]
(a) only stannic chloride
(b) boron trifluoride and stannic chloride
(c) boron trifluoride and stannous chloride
(d) only boron trifluoride
Show Answer
Solution:
- (c) Because of electron deficiency, boron trifluoride and stannous chloride are lewis acid.
Vacant $d$-orbitals are available with stannic chloride, hence it can also accept pair of electrons and act as a lewis acid.
