Which of the following statements are correct. Answer based on the given figure,

(i) The two bridged hydrogen atoms and the two boron atoms lie in one plane;

(ii) Out of six B–H bonds two bonds can be described in terms of 3 centre 2-electron bonds.

(iii) Out of six B-H bonds, four B-H bonds can be described in terms of 3 centres 2 electron bonds;

(iv) The four-terminal B-H bonds are two centre-two electron regular bonds.

Answers (1)

The answer is the option: -

(i) The two bridged hydrogen atoms and the two boron atoms lie in one plane.
(ii) Out of six B – H, bonds two bonds can be described in terms of 3 centre 2-electron bonds.
(iv) The four-terminal B – H bonds are two centre-two electron regular bonds.

The two boron atoms have a sp^{3}-hybrid state. Only three atoms have one electron each while the fourth is empty. They lie in one plane and two bridging hydrogen atoms.
