In 
distance is shorter than what is expected theoretically because (X = F, Cl, Br, I)
A
hybridization of B is responsible for shorter B – X distance.
B
B – X has a double bond character due to back – bonding
C
Dimerisation takes place in 
which is responsible for shorter B – X distance.
which is responsible for shorter B – X distance.
D
Due to large size of X, B – X distance decreases.
Text Solution
Verified by ExpertsThe correct answer is:
B
Due to back – bonding, B – X in 
has double bond character which because of resonance results in shorter B – X distance.
