Question

Identify the statement(s) that is/are correct as far as structure of diborane is concerned :

• A. There are two bridging hydrogen atoms in diborane.
• B. Each boron atom forms four bonds in diborane.
• C. The hydrogen atoms are not in the same plane in diborane.
• D. All B-H bonds in diborane are similar.

Answer 1

Answer: (A), (B), (C)

The correct options are
A There are two bridging hydrogen atoms in diborane.
B Each boron atom forms four bonds in diborane.
C The hydrogen atoms are not in the same plane in diborane.

$B_2{H}_6$ has two types of $B-H$ bonds - terminal and bridge.

Hydrogen atoms are not in the same plane in diborane as central atom B is $s{p}^3$ hybridised.
