The correct statement about B H is 2 6 o 3 (A) All B – H – B angles are of 120 (B) Its fragment, BH , behaves as a Lewis base (C) The two B – H – B bonds are not of same length (D) Terminal B – H bond

Question

The correct statement about B H is 2 6 o 3

(A) All B – H – B angles are of 120
(B) Its fragment, BH , behaves as a Lewis base
(C) The two B – H – B bonds are not of same length
(D) Terminal B – H bonds have less p-character when compared to bridging bonds

Prashant Kotian · Accepted Answer

Correct answer: C) THE TWO B – H – B BONDS ARE NOT OF SAME LENGTH. have 4 2c-2e bonds and 2 3c-2e bonds. Bridging bonds have larger bond length than terminal bonds. Angle between terminal bonds is more than angle between bridging bonds if all 4 terminal bonds are in one plane then bridging bonds are in perpendicular plane. As terminal bridge % s-character B.A. As external bond has more %s-character or less % p-character
