Q66 / 200 · NEET 2022 (Phase 1) · Chemistry

Which of the following statement is not correct about diborane?

  • A
    The four terminal B-H bonds are two centre two electron bonds.
  • B
    The four terminal Hydrogen atoms and the two Boron atoms lie in one plane.
  • Correct answer
    C
    Both the Boron atoms are sp2 hybridised.
  • D
    There are two 3-centre-2-electron bonds.

Solution

Boron atoms form 4 bonds and are sp3 hybridised.

Figure    

The four terminal B-H bonds are two centre two electron bonds.While There are two 3-centre-2-electron bonds in between both B atoms. The four terminal Hydrogen atoms and the two Boron atoms lie in the same plane.

Hence, the correct answer is option: 'C'.
