Question

Match the List-I (Reactions) with List-II (Reaction name) and choose the correct option.

List-I (Reactions) (A) CH3-CH2-Cl $\xrightarrow[\text{Acetone}]{\text{NaI}}$ (B) CH3-CH2-OH $\xrightarrow[\text{443 K}]{\text{Conc. H}_2SO_4}$ (C) CH3-CH2-OH $\xrightarrow[\text{413 K}]{\text{Conc. H}_2SO_4}$ (D) R-CH2OH $\xrightarrow[\text{Heat}]{\text{Cu or Ag}}$

List-II (Name of Reaction) (P) Finkelstein Reaction (Q) Dehydration of alcohol to alkene (R) Dehydration of alcohol to ether (S) Catalytic oxidation of primary alcohol

• A. A-P, B-Q, C-R, D-S
• B. A-Q, B-P, C-S, D-R
• C. A-R, B-S, C-P, D-Q
• D. A-S, B-R, C-Q, D-P

Answer 1

Answer: (A)

A-P, B-Q, C-R, D-S

Answer 2

(A) The reaction of an alkyl halide with sodium iodide in a polar aprotic solvent like acetone is known as the Finkelstein reaction, where halogen exchange occurs.

(B) Dehydration of ethanol with concentrated sulfuric acid at a high temperature (443 K) leads to the formation of ethene, an alkene.

(C) Dehydration of ethanol with concentrated sulfuric acid at a lower temperature (413 K) results in the formation of diethyl ether.

(D) The catalytic oxidation of a primary alcohol using copper or silver as a catalyst produces an aldehyde.
