Identify the statement that is not correct as far as structure of dibroane is concerned

there are two bridging hydrogen atoms in diborane

each boron atom forms four bonds in diborane

all `B-H` bonds in diborane are similar

the hydrogen atoms are not in the same plane in diborane

Text Solution

Verified by Experts

The correct Answer is:

Diborane possess four `B-H` covalent bonds and two three centred (two electrons) `B-H-B` or hydrogen bridge bonds. These bonds are also known as banana bonds.
