Question

Why back bonding occurs in boron halide but not in alluminium halide

Answer 1

Answer:

Due to large difference in 3p orbital of aluminum

Explanation:

hope the answer will help you

Answer 2

★ It is because of the following reasons:-

→ As we know, only the orbitals which are of small atoms and similar in size can form a back bond.

→ Here, by taking alluminium, we know that the 3p orbitals of Al and Cl are comparatively larger in size.

→ And this literally increases the bond length.

→ Therefore, it can not attain the double bond character by back bonding.
