Natural rubber on complete ozonolysis $\left(\mathrm{O}_3 / \mathrm{Zn}-\mathrm{H}_2 \mathrm{O}\right)$ gives compound $\mathbf{X}$ as the major product. $\mathbf{X}$ gives positive iodoform and Tollen's tests. $\mathbf{X}$ on heating with aqueous NaOH gives $\mathbf{Y}$ as the major product. $\mathbf{Y}$ is

Considering LiBH₄ reduces an ester group to the corresponding alcohol and does not reduce a carboxylic acid group, the correct statement about the major products P, Q, R and S is:

The List-II contains products obtained from the reaction of compounds in List-I with $O_3$/Zn-$H_2O$ followed by cyclization (via more stable enolate) in the presence of aqueous NaOH. Match each entry in List-I with appropriate entry in List-II and choose the correct option.

List-I	List-II
(P)	(1)
(Q)	(2)
(R)	(3)
(S)	(4)
	(5)

Match the major products obtained in the reactions given in List-I with the corresponding structures in List-II and choose the correct option.

List-I	List-II
(P)	(1)
(Q)	(2)
(R)	(3)
(S)	(4)
