JEE Chemistry 2024 Question with Solution

Given: The solution states that the given structure has two double bonds, and each double bond can show geometrical isomerism.

Find: The number of geometrical isomers possible for the given structure.

For each double bond, two geometrical arrangements are possible: cis or trans.

So the total number of possibilities is

$$2 \times 2 = 4$$

Thus, the total number of geometrical isomers is $4$.

Therefore, the correct option is C.

Given: One part of the solution mentions counting possible configurations using stereochemical choices and then accounting for equivalence.

Find: The number of unique geometrical isomers.

The solution notes an initial count of

$$2^3 = 8$$

but then states that because of symmetry, some configurations are equivalent.

After removing equivalent arrangements, the number of unique geometrical isomers becomes $4$.

Therefore, the number of geometrical isomers possible is $4$, so the correct option is C.
