Question

Which of the following is the electron deficient molecule? (A)  B2H6 (B)  C2H6 (C) PH3 (D) SiH4

Tardigrade Admin · Accepted Answer

B2H6 is electron deficient molecule because boron atom has three half-filled orbitals in excited state. The structure of B2H6 is represented as follows: In it two electrons of a B - H bond are involved in formation of three centre bond, these bonds are represented as dotted lines.
