Question

Identify the correct statement for B 2 H 6 from those given below. (A) In B 2 H 6 , all B - H bonds are equivalent. (B) In B 2 H 6 , there are four 3 -centre- 2 -electron bonds. (C) B 2 H 6 is a Lewis acid. (D) B 2 H 6 can be synthesized from both BF 3 and NaBH 4 . (E) B 2 H 6 is a planar molecule. Choose the most appropriate answer from the options given below :

B 2 H 6 have four 2 c - 2 e bonds and two 3 c - 2 e bonds. Bridging bonds have larger bond length than terminal bonds. Angle between terminal bonds is more than angle between bridging bonds if all 4 terminal bonds are in one plane then bridging bonds are in perpendicular plane. 3 NaBH 4 + 4 BF 3 ⟶ ether 450 K 3 NaBF 4 + 2 B 2 H 6 Therefore we can say that only statement (C) and (D) are correct.
