In the following structure, the double bonds are marked as I, II, III and IV
Geometrical isomerism is not possible at site (s) :
Geometrical isomerism is not possible at site (s) :
Show Hint
- III
- I
- I and III
- III and IV
The Correct Option is B
Solution and Explanation
Double bond I: the terminal carbon carries two identical \(\mathrm{CH_3}\) groups, so no geometrical isomerism.
Double bond II: one carbon has \(\mathrm{CH_3}\) and a chain, the other has H and a \(\mathrm{CH_2}\) chain; all different, so it is possible.
Double bond III: one carbon has \(\mathrm{CH_3}\) and a \(\mathrm{CH_2}\) chain; the other has \(\mathrm{CH_3}\) and the carbon of bond IV: different, so it is possible.
Double bond IV: one carbon has \(\mathrm{CH_3}\) and the carbon of bond III; the other has \(\mathrm{CH_3}\) and \(\mathrm{C_2H_5}\): different, so it is possible.
Only site I lacks geometrical isomerism.
Answer: (2) I

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:
