Which of the following statements is NOT correct about diborane?

  1. The four terminal Hydrogen atoms and the two Boron atoms lie in one plane.
  2. Both the Boron atoms are \( sp^2 \) hybridised.
  3. There are two 3-centre-2-electron bonds.
  4. The four terminal B−H bonds are two centre two electron bonds.

Correct answer · Option 2

Both the Boron atoms are \( sp^2 \) hybridised.

Explanation

In diborane \( B_2H_6 \), both boron atoms are \( sp^3 \) hybridized, not \( sp^2 \). Thus statement (B) is incorrect.
