Question

In the structure of diborane 

(i) All hydrogen atoms lie in one plane and boron atoms lie in a plane perpendicular to this plane. 

(ii) 2 boron atoms and 4 terminal hydrogen atoms lie in the same plane and 2 bridging hydrogen atoms lie in the perpendicular plane. 

(iii) 4 bridging hydrogen atoms and boron atoms lie in one plane and two terminal hydrogen atoms lie in a plane perpendicular to this plane. 

(iv) All the atoms are in the same plane.

Answer 1
