The major products obtained from the reactions in List-II are the reactants for the named reactions mentioned in List-I. Match List-I with List-II and choose the correct option.

P →2; Q→4 ; R →1; S →3
P →1; Q→3 ; R →5; S →2
P →3; Q→2 ; R →1; S →4
P →3; Q→4 ; R →5; S →2
To solve the problem, we'll analyze the named reactions in List-I and identify the corresponding major products from List-II. Let's match each:
| 1. Aldol Condensation | A reaction involving the formation of β-hydroxy ketone (aldol) followed by dehydration resulting in α,β-unsaturated ketone. In List-II, this product is associated with compound 4. |
| 2. Finkelstein Reaction | A halogen exchange reaction used to convert alkyl chlorides/bromides to iodides using sodium iodide, corresponding to compound 5 in List-II. |
| 3. Sandmeyer Reaction | A substitution reaction that converts diazonium salts to aryl halides, often involving the replacement of a diazo group with a halide ion. The right match here is compound 2 from List-II. |
| 4. Williamson Ether Synthesis | A reaction for the synthesis of ethers from alkoxides and alkyl halides, matching with compound 3 in List-II. |
Based on these connections, we get:
Thus, the correct option is: P →3; Q→4 ; R →5; S →2
Correct option is (D) P → 3; Q → 4; R → 5; S → 2 (P) → (3)





Let $ P(x_1, y_1) $ and $ Q(x_2, y_2) $ be two distinct points on the ellipse $$ \frac{x^2}{9} + \frac{y^2}{4} = 1 $$ such that $ y_1 > 0 $, and $ y_2 > 0 $. Let $ C $ denote the circle $ x^2 + y^2 = 9 $, and $ M $ be the point $ (3, 0) $. Suppose the line $ x = x_1 $ intersects $ C $ at $ R $, and the line $ x = x_2 $ intersects $ C $ at $ S $, such that the $ y $-coordinates of $ R $ and $ S $ are positive. Let $ \angle ROM = \frac{\pi}{6} $ and $ \angle SOM = \frac{\pi}{3} $, where $ O $ denotes the origin $ (0, 0) $. Let $ |XY| $ denote the length of the line segment $ XY $. Then which of the following statements is (are) TRUE?
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
