Q. In $diborane$ the two $H - B - H$ angles are nearly
A) $95{^\circ}\ ,\ 120{^\circ}$
B) $60{^\circ}\ ,\ 120{^\circ}$
C) $120{^\circ}\ ,180{^\circ}$
D) $95{^\circ}\ ,\ 150{^\circ}$
Explanation
(a)
$Dilthey\$in 1921 proposed a bridge structure for diborane. Four hydrogen atoms, two on the left and two on the right known as terminal $hydrogens\$and two boron atoms lie in the same plane. Two hydrogen atoms forming bridges, one above and other below, lie in a perpendicular to the rest of molecule
