In diborane, the two \[H-B-H\] angles are nearly:

A) \[{{60}^{o}},{{120}^{o}}\]            

B)        \[{{95}^{o}},{{120}^{o}}\]            

C)        \[{{95}^{o}},{{150}^{o}}\]      

D)        \[{{120}^{o}},{{180}^{o}}\]

Correct Answer: B

Solution :

Structure of diborane is as follows: Thus the \[H-B-H\] angles are nearly \[{{97}^{o}}\], \[{{120}^{o}}\].
