Correct Option - 4
Detailed Solution:B2H6 has 4 2 c -2e bonds and 2 3c-2e bonds.
Bridging (B-H) bonds have more value of bond- length then terminal (B – H) bonds
Bridging bonds are in one plane, but terminal bonds are in perpendicular plane.
Due to presence of (3c-2e) bonds, it behaves as electrons deficient and prone to get attached by lewis base.
