Identify the correct statements for B2H6from those given below:(A) In ...
The correct statements for B2H6 are (C) and (D) only.

(C) B2H6 is a Lewis acid:
A Lewis acid is a species that can accept an electron pair from a Lewis base. B2H6 can act as a Lewis acid because it has an electron-deficient boron atom that can accept a pair of electrons.

(D) B2H6 can be synthesized from both BF3 and NaBH4:
B2H6 can be synthesized from BF3 by reacting it with LiAlH4. The reaction proceeds as follows:
BF3 + LiAlH4 → AlH3 + LiBF4
AlH3 + B2H6 → 2BH3 + Al

B2H6 can also be synthesized from NaBH4 by reacting it with BF3 etherate. The reaction proceeds as follows:
NaBH4 + BF3 etherate → NaBF4 + B2H6

The incorrect statements are:

(A) In B2H6, all B-H bonds are equivalent:
In B2H6, the B-H bonds are not equivalent. The molecule has a three-center, two-electron bond, also known as a banana bond, where two hydrogen atoms bond with one boron atom. These bonds are weaker and longer than typical B-H bonds.

(B) In B2H6, there are four 3-centre-2-electron bonds:
In B2H6, there are a total of six 3-center, 2-electron bonds. Each boron atom forms three such bonds with hydrogen atoms, resulting in a total of six bonds.

(E) B2H6 is a planar molecule:
B2H6 is not a planar molecule. It adopts a three-dimensional structure with a D2h symmetry. It has a puckered structure where the two boron atoms are not in the same plane.

Identify the correct statements for B2H6from those given below:(A) In ...
Structure of B2H6:

It has two 3-centre-2-electron bonds and four 2-centre-2-electron bonds.
Hence, all B-H bonds are not equivalent.
It is an electron deficient compound as the octet of boron is incomplete.
Hence, it can behave as a Lewis acid.
It can be synthesized from both BF3 and NaBH4.

It is a non-planar molecule.
Hence, only statements (C) and (D) are correct.
