Match the chemical conversions in List I with the appropriate reagents in List II and select the correct answer using the code given below the lists:

List II
1.	(i) $Hg (OAc)_{2}$ ; (ii) $NaBH_{4}$
2.	NaOEt
3.	Et-Br
4.	(i) $BH_{3}$ ; (ii) $H_{2} O_{2} / NaOH$

(A)P-2, Q-3, R-1, S-4✓ Correct
(B)P-3, Q-2, R-1, S-4
(C)P-2, Q-3, R-4, S-1
(D)P-3, Q-2, R-4, S-1

Answer: (A)

Solution

Matching the conversions with reagents:

P: Elimination reaction (E2) → NaOEt (2)

Q: Williamson ether synthesis → Et-Br (3)

R: Oxymercuration-demercuration (Markovnikov addition) → (i)

Hg (OAc)_{2}

; (ii)

NaBH_{4}

(1)

S: Hydroboration-oxidation (anti-Markovnikov addition) → (i)

BH_{3}

; (ii)

H_{2} O_{2} / NaOH

(4)

Code: P-2, Q-3, R-1, S-4
