Question

In the structure of diborane,
(a) All hydrogen atoms lie in one plane and boron atoms
lie in a plane perpendicular to this plane
(b) 2 boron atoms and 4 terminal hydrogen atoms lie in the
same plane and 2 bridging hydrogen atoms lie in the
perpendicular plane
(c) 4 bridging hydrogen atoms and boron atoms lie in one
plane and two terminal hydrogen atoms lie in a plane
perpendicular to this plane
(d) All the atoms are in the same plane
