A mixture of hydrocarbons contain three compounds P, Q and R. Q and R are stereoisomers. When this mixture is treated with cold, concentrated H2SO4 , Q and R got a bsorbed while Premained unreacted , forming a separate layer at surface. After separation of P, the acid solution is heated and the hydrocarbons Q and R recovered, containing predominantly Q. When vaporised mixture of P, Q and R is passed over heated Ni containing adsorbed H2 gas, a single alkane of six carbon was obtained. Also, Q on treatment with Br2/CCI4 in the presence of FeBr3, a meso dibromide is formed.
Q. Q and R respectively are
- a)c/s-2-hexene and frans-2-hexene
- b)trans and c/s-3-hexene
- c)2, 3-dimethyl-2-butene
- d)cis and frans-3-methyl-2-pentene
Correct answer is option 'B'. Can you explain this answer?

A mixture of hydrocarbons contain three compounds P, Q and R. Q and R ...
Explanation:
The given mixture of hydrocarbons contains three compounds P, Q, and R. Q and R are stereoisomers, which means they have the same molecular formula but differ in their spatial arrangement.
Treatment with cold, concentrated H2SO4:
When the mixture is treated with cold, concentrated H2SO4, Q and R get absorbed while P remains unreacted, forming a separate layer on the surface. This indicates that Q and R are more reactive towards H2SO4 compared to compound P.
Separation of P:
After the separation of P, the acid solution is heated. This suggests that compound P is stable under heating conditions.
Recovery of Q and R:
Upon heating the acid solution, Q and R are recovered. The recovered mixture contains predominantly Q. This indicates that Q is the major product formed during the heating process.
Passing vaporized mixture over heated Ni:
When the vaporized mixture of P, Q, and R is passed over heated Ni containing adsorbed H2 gas, a single alkane of six carbons is obtained. This suggests that the mixture of hydrocarbons contains an alkene with six carbons, which is converted to the corresponding alkane in the presence of heated Ni and H2 gas.
Treatment of Q with Br2/CCI4 in the presence of FeBr3:
When Q is treated with Br2/CCI4 in the presence of FeBr3, a meso dibromide is formed. This indicates that Q is an unsaturated compound with double bonds and reacts with Br2 to form a dibromide.
Based on the above observations, we can conclude the following:
- Compound P remains unreacted with H2SO4 and is stable under heating conditions.
- Compound Q is the major product obtained upon heating the acid solution and reacts with Br2 to form a meso dibromide.
- Compound R is a stereoisomer of Q and is absorbed by H2SO4, indicating its reactivity towards the acid.
Therefore, the correct answer is option B: trans and c/s-3-hexene, which corresponds to the stereoisomers Q and R, respectively.
