Given below are the statements about diborane
(a) Diborane is prepared by the oxidation of \(\mathrm{NaBH_4}\) with \(\mathrm{I_2}\)
(b) Each boron atom is in \(sp^2\) hybridized state
(c) Diborane has one bridged 3 centre-2-electron bond
(d) Diborane is a planar molecule
The option with correct statements is :
(a) Diborane is prepared by the oxidation of \(\mathrm{NaBH_4}\) with \(\mathrm{I_2}\)
(b) Each boron atom is in \(sp^2\) hybridized state
(c) Diborane has one bridged 3 centre-2-electron bond
(d) Diborane is a planar molecule
The option with correct statements is :
Show Hint
- (c) and (d) only
- (a) only
- (c) only
- (a) and (b) only
The Correct Option is B
Solution and Explanation
(b) In diborane each boron is \(sp^3\) hybridised: incorrect.
(c) Diborane has two bridging 3-centre-2-electron (B-H-B) bonds, not one: incorrect.
(d) Four terminal B-H bonds lie in one plane, but the two bridge H atoms lie above and below it, so the molecule is non-planar: incorrect.
Only (a) is correct.
Answer: (2) (a) only

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
