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. If Q and R are treated separately with HBr, the correct statement concerning addition product is
- a)A single bromoalkane is formed in both cases
- b)A pair of diastereomers are formed in both cases
- c)A pair of enantiomers in equal amounts are formed in both ca
- d)None of the above
Correct answer is option 'C'. Can you explain this answer?

A mixture of hydrocarbons contain three compounds P, Q and R. Q and R ...
Mixture of hydrocarbons:
- Contains three compounds: P, Q, and R
- Q and R are stereoisomers
Treatment with cold, concentrated H2SO4:
- Q and R get absorbed
- P remains unreacted and forms a separate layer at the surface
Separation of P:
- Acid solution is heated
- Q and R, predominantly Q, are recovered
Vaporization and passing over heated Ni with H2 gas:
- A single alkane of six carbon is obtained
Treatment of Q with Br2/CCI4 in the presence of FeBr3:
- Meso dibromide is formed
Treatment of Q and R separately with HBr:
- The correct statement concerning the addition product is that a pair of enantiomers in equal amounts are formed in both cases (option C)
Explanation:
The reaction of Q and R with HBr results in the addition of a bromine atom to the hydrocarbon. Since Q and R are stereoisomers, they have the same molecular formula but differ in their spatial arrangement. When treated with HBr, both Q and R will form pairs of enantiomers, which are mirror images of each other.
Enantiomers have the same connectivity of atoms but differ in their spatial arrangement. They are non-superimposable mirror images of each other. When a chiral molecule reacts with an achiral reagent like HBr, it can form a pair of enantiomers.
In this case, Q and R are stereoisomers, which means they have the same molecular formula and connectivity of atoms but differ in their spatial arrangement. Therefore, when treated separately with HBr, both Q and R will form pairs of enantiomers. Since the question states that Q and R are stereoisomers, the correct statement is that a pair of enantiomers in equal amounts are formed in both cases (option C).
