In BX3, B – X distance is shorter than what is expected theoretically because (X = F, Cl, Br, I)
A.sp3 hybridisation of B is responsible for shorter
B.B – X has a double bond character due to back-✓ Correct
C.Dimerisation takes place in BX3 which is responsible
D.Due to large size of X, B – X distance decreases.
Explanation
Due to back bonding, bond length decreases between X and B
