Which of the following is correct for the structure of diborane?

Options

  1. AIt contains four ( 2 c , 2 e )   covalent bonds and two ( 3 c , 2 e )   covalent bonds.
  2. BIt contains three ( 2 c , 2 e )   covalent bonds and three ( 3 c , 2 e ) covalent bonds.
  3. CIt contains two   ( 2 c , 2 e ) covalent bonds and four ( 3 c , 2 e ) covalent bond.
  4. DIt contains six ( 2 c , 2 e ) covalent bonds.

Correct answer

A. It contains four ( 2 c , 2 e )   covalent bonds and two ( 3 c , 2 e )   covalent bonds.

Step-by-step solution

Normal single bond called 2 C - 2 e bond and bridge bond of H called 3 C - 2 e bond.
