According to the given figure, which of the following statements is incorrect?
Options
- AThe 2 bridged hydrogen atoms and 2 boron atoms lie in one plane.
- BOut of 6 ~B - H bonds two bonds can be described in terms of 3 centre 2-electron bonds.
- COut of 6 ~B - H bonds four bonds can be described in terms of 3 centre 2-electron bonds.
- DThe four terminal B - H bonds are 2 centre 2 electron regular bonds.
Correct answer
C. Out of 6 ~B - H bonds four bonds can be described in terms of 3 centre 2-electron bonds.
Step-by-step solution
In B ₂ H ₆ there is only 2 hydrogen, which are 3 centered 2 electron bond, thus statement (3) is incorrect.
