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 $ \mathbb{R} $ denote the set of all real numbers. Then the area of the region $$ \left\{ (x, y) \in \mathbb{R} \times \mathbb{R} : x > 0, y > \frac{1}{x},\ 5x - 4y - 1 > 0,\ 4x + 4y - 17 < 0 \right\} $$ is
As shown in the figures, a uniform rod $ OO' $ of length $ l $ is hinged at the point $ O $ and held in place vertically between two walls using two massless springs of the same spring constant. The springs are connected at the midpoint and at the top-end $ (O') $ of the rod, as shown in Fig. 1, and the rod is made to oscillate by a small angular displacement. The frequency of oscillation of the rod is $ f_1 $. On the other hand, if both the springs are connected at the midpoint of the rod, as shown in Fig. 2, and the rod is made to oscillate by a small angular displacement, then the frequency of oscillation is $ f_2 $. Ignoring gravity and assuming motion only in the plane of the diagram, the value of $\frac{f_1}{f_2}$ is:
Let $ a_0, a_1, ..., a_{23} $ be real numbers such that $$ \left(1 + \frac{2}{5}x \right)^{23} = \sum_{i=0}^{23} a_i x^i $$ for every real number $ x $. Let $ a_r $ be the largest among the numbers $ a_j $ for $ 0 \leq j \leq 23 $. Then the value of $ r $ is ________.
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.
