JEE Main 2022 Chemistry question
Identify the correct statement for from those given below: (A) In , all B-H bonds are equivalent. (B) In , there are four 3-centre-2-electron bonds. (C) is a Lewis acid. (D) can be synthesized from both and . (E) is a planar molecule. Choose the most appropriate answer from the options given below:
Answer: (3)
Solution
has two 3-centre-2-electron (B–H–B) bonds and four 2-centre-2-electron bonds, so not all B–H bonds are equivalent (A, B false). It is electron deficient and behaves as a Lewis acid (C true). It
