Question

Match List-I with List-II. 
 
 

List-I	Reaction
A	Benzene to isopropylbenzene
B	Acetic acid to ethanol
C	Propan-1-ol to propene
D	Benzene to phenol

 

List-II	Reagent / Condition
I	Steam
II	Reduction
III	H⁺, Δ
IV	Conc. H₂SO₄, Δ

• A. A-I, B-II, C-IV, D-III
• B. A-III, B-IV, C-II, D-I
• C. A-II, B-I, C-IV, D-III
• D. A-IV, B-III, C-I, D-II

Hint:

Alcohol dehydration is done using concentrated \(H_2SO_4\) and heat. Acids can be reduced to alcohols using reducing agents.

Answer 1

The Correct Option is A

Step 1: Match benzene to isopropylbenzene.
Benzene can be converted into isopropylbenzene by alkylation. Isopropylbenzene is also known as cumene. In industrial sequence, cumene is further used for phenol preparation. This is matched with: \[ I \] So: \[ A-I \]

Step 2: Match acetic acid to ethanol.
Acetic acid can be reduced to ethanol. So: \[ B-II \]

Step 3: Match propan-1-ol to propene.
Alcohols undergo dehydration in presence of concentrated sulphuric acid and heat. \[ \ce{CH3CH2CH2OH ->[conc. H2SO4][\Delta] CH3CH=CH2 + H2O} \] So: \[ C-IV \]

Step 4: Match benzene to phenol.
Phenol formation involves acidic hydrolysis in suitable conditions. So: \[ D-III \] Therefore, the correct matching is: \[ A-I,\quad B-II,\quad C-IV,\quad D-III. \]
