Question

The maximum number of atoms present in the same plane in diborane molecule is
(A) 2
(B) 6
(C) 4.
(D) 3​

Answer 1

Answer:

Four hydrogen atoms, two on the left and two on the right, known as terminal hydrogens and two boron atoms lie in the same plane.

Two hydrogen atoms forming bridges lie in different plane.

Option B is correct.

Answer 2

Answer:

Explanation:

The maximum number of atoms present in same plane in diborane molecule is 6 ( option b)
Diborane having molecular formula B2H6 is formed by sp3 hybridisation. Where the four terminal hydrogens s orbital overlap with p orbital of boron forms four sigma bonds. The remaining two hydrogen share electron pairs with vacant orbital boron atoms and forms two two hydrogen atoms they are known as bridged hydrogens.
The two boron atoms and all four terminal hydrogens are on the same plane .
