|
(B) lodoform |
(II) Ozone depletion |
|
(C) ${S_N}^1$ |
(III) Antiseptic |

(D) Carbon tetrachloride |
(IV) Inversion |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
(A) $S_N2 \rightarrow$ (IV) Inversion: $S_N2$ reactions proceed through backside attack on the carbon center, causing Walden inversion of configuration.
(B) Iodoform $\rightarrow$ (III) Antiseptic: Iodoform $(\text{CHI}_3)$ is used in medicine for wound dressing due to its mild antiseptic and disinfectant properties.
(C) $S_N1 \rightarrow$ (I) Racemization: $S_N1$ reactions form a planar carbocation intermediate, allowing the nucleophile to attack from either side, leading to racemization.
(D) Carbon tetrachloride $\rightarrow$ (II) Ozone depletion: $\text{CCl}_4$ releases chlorine radicals in the stratosphere that destroy ozone molecules, contributing to ozone layer depletion.
