SATHEE: Chemical Bonding and Molecular Structure

Chemical Bonding and Molecular Structure - Result Question 6

####6. Which of the following compounds has a 3-centre bond?

[1996]

(a) Diborane

(b) Carbon dioxide

(d) Ammonia

Show Answer

Solution:

The bond represented by dots form the 3-centred electron pair bond.

The idea of three centred electron pair bond $B - H - B$ bridges is necessary because diborane does not have sufficient electrons to form normal covalent bonds. It has only 12 electrons instead of 14 that are required to give simple ethane like structure.
