Text Solution

Verified by Experts

The correct Answer is:
B
2-C+2H+2Br=186
`Br_(2)-C=CH_(2)` and `underset("2-Geometrical isomer")(Br-CH=CH-Br)`
We know that alkene have minimum one double bond. If we take 2-Bromine atoms it will have 160 mol. Weight so remaining will be 2C and 2-H there 2-Br atoms placed at one carbon or both carbon can have one Br respectively. which will give geometrical isomerism (2-Forms).
