The structure of diborane (B₂H₆) contains :
A.four 2C-2e bonds and two 3C-2e bonds✓ Correct
B.two 2C-2e bonds and four 3C-2e bonds
C.two 2C-2e bonds and two 3C-3e bonds
D.four 2C-2e bonds and four 3C-2e bonds
Explanation
The structure of Diborane is shown as- There are four hydrogens which are connected to B atoms by simple covalent bonds. These are 2 centered- 2 electron B-H bonds. And the two hydrogen atoms are connected to 2 boron atoms by bridge. These are 3- centred- 2- electron B-H-B bonds.
