Which of the following statement is not correct about diborane?
Options
- AThe four terminal B - H bonds are two centre two electron bonds.
- BThe four terminal Hydrogen atoms and the two Boron atoms lie in one plane.
- CBoth the Boron atoms are sp 2 hybridised.
- DThere are two 3 -centre- 2 -electron bonds.
Correct answer
C. Both the Boron atoms are sp 2 hybridised.
Step-by-step solution
Boron atoms form 4 bonds and are sp 3 hybridised. The four terminal B - H bonds are two centre two electron bonds.While There are two 3 -centre- 2 -electron bonds in between both B atoms. The four terminal Hydrogen atoms and the two Boron atoms lie in the same plane.
