JEE Main Chemistry question

Identify the statement that is not correct as far as the structure of diborane is concerned

(A)Each boron atom forms four bonds in diborane
(B)There are two bridging hydrogen atoms in diborane
(C)The hydrogen atoms are not in the same plane in diborane
(D)All B–H bonds in diborane are similarCorrect

Answer: (D)

Solution

Diborane genuinely has two bridging hydrogens (B), and these bridging hydrogens lie out of the plane of the four terminal hydrogens and two borons (C); each boron is also 4-coordinate overall (two terminal H plus two bridge H),
