Which of the following order is/are INCORRECT.
Options:(select one or more)
Answer:
A, B, C
Solution:
(A) Incorrect: Both BF₃ and BCl₃ are trigonal planar, so the maximum number of atoms in one plane is the same (4 atoms).
(B) Incorrect: B–F bond length < B–Cl bond length, so BF₃ > BCl₃ is wrong.
(C) Incorrect: Both molecules have a bond angle of 120°, so there is no greater-than relationship.
(D) Correct: Back bonding is greater in BF₃ than in BCl₃ because of effective 2p–2p overlap.
Correct Answer: (A), (B), (C)
