Direction (Q. Nos. 14 - 16) This section contains a paragraph, describing theory, experiments, data, etc.
Three questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).
Passage
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. What is P ?
  • a)
    Hexane
  • b)
    2, 3-dimethyl butane
  • c)
    2-methyl pentane
  • d)
    3-methyl pentane
Correct answer is option 'A'. Can you explain this answer?

**Explanation:**

P is the compound that remains unreacted and forms a separate layer at the surface when the mixture of hydrocarbons is treated with cold, concentrated H2SO4.

The passage mentions that Q and R are stereoisomers, which means they have the same molecular formula but differ in the spatial arrangement of atoms. Q and R get absorbed when treated with H2SO4, indicating that they undergo a chemical reaction. On the other hand, compound P remains unreacted and forms a separate layer, indicating that it is not affected by the H2SO4.

To determine the identity of P, we need to consider the properties and reactions mentioned in the passage.

- The passage states that when the acid solution (after separation of P) is heated, hydrocarbons Q and R are recovered, containing predominantly Q. This suggests that Q is more stable or less reactive compared to R.

- The passage also mentions that when a vaporized mixture of P, Q, and R is passed over heated Ni containing adsorbed H2 gas, a single alkane of six carbon is obtained. This indicates that the alkane is formed by the hydrogenation of the unsaturated hydrocarbons present in the mixture. Since P is unreactive with H2SO4, it is likely to be an alkane.

Based on the information given, we can conclude that P is an alkane that is unreactive with concentrated H2SO4 and is not a stereoisomer of Q and R. Among the given options, only hexane (option A) fits these criteria. Therefore, the correct answer is option A) Hexane.
