Which of the following statements is true regarding the structure and properties of ?
- A.It contains two 3-center-2-electron bonds.
- B.All bonds in diborane are of equal length.
- C.It is a planar molecule.
- D.It acts as a strong Bronsted-Lowry acid.
Show correct answer & step-by-step solution
Correct answer: A — It contains two 3-center-2-electron bonds.
Solution
- Diborane has a bridged structure where two hydrogen atoms bridge the two boron atoms.
- The bridging bonds are 3-center-2-electron bonds.
- The terminal bonds are normal 2-center-2-electron covalent bonds.
- Hence the answer is (A).
