Given below are the statements about diborane (a) Diborane is prepared by the oxidation of NaBH 4 with I 2 (b) Each boron atom is in sp 2 hybridized state (c) Diborane has one bridged 3 centre- 2 -electron bond (d) Diborane is a planar molecule The option with correct statement(s) is
Options
- A(c) and (d) only
- B(a) only
- C(c) only
- D(a) and (b) only
Correct answer
B. (a) only
Step-by-step solution
Diborane is prepared by the reaction of NaBH 4 with I 2 . 2 NaBH 4 + I 2 → B 2 H 6 + 2 NaI + H 2 In diborane, B is sp 3 hybridized. It is non-planar molecule and it has two 3 c - 2 e - bonds.
