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
The Correct Option is D
Approach Solution - 1
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:
- P (Aldol Condensation) → 3
- Q (Finkelstein Reaction) → 4
- R (Sandmeyer Reaction) → 5
- S (Williamson Ether Synthesis) → 2
Thus, the correct option is: P →3; Q→4 ; R →5; S →2
Approach Solution -2
Correct option is (D) P → 3; Q → 4; R → 5; S → 2 (P) → (3)

A temperature difference can generate e.m.f. in some materials. Let $ S $ be the e.m.f. produced per unit temperature difference between the ends of a wire, $ \sigma $ the electrical conductivity and $ \kappa $ the thermal conductivity of the material of the wire. Taking $ M, L, T, I $ and $ K $ as dimensions of mass, length, time, current and temperature, respectively, the dimensional formula of the quantity $ Z = \frac{S^2 \sigma}{\kappa} $ is:

Organic Chemistry - Some Basic Principles and Techniques
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.
