Match the structures in Column-$I$ with their common names in Column-$II$ and $\text{IUPAC}$ names in Column-$III$.
Column-$I$ Column-$II$ Column-$III$ $(A) \ HO-CH_2-CH_2OH$ $(1) \ \text{sec-Butyl alcohol}$ $(i) \ \text{Ethane-1,2-diol}$ $(B) \ CH_3-CH(OH)-CH_2CH_3$ $(2) \ \text{Isopropyl alcohol}$ $(ii) \ \text{2,2-Dimethylpropan-1-ol}$ $(C) \ CH_3-CH(OH)-CH_3$ $(3) \ \text{Ethylene glycol}$ $(iii) \ \text{Butan-2-ol}$ $(D) \ (CH_3)_3C-CH_2OH$ $(4) \ \text{Neopentyl alcohol}$ $(iv) \ \text{Propan-2-ol}$
| Column-$I$ | Column-$II$ | Column-$III$ |
| $(A) \ HO-CH_2-CH_2OH$ | $(1) \ \text{sec-Butyl alcohol}$ | $(i) \ \text{Ethane-1,2-diol}$ |
| $(B) \ CH_3-CH(OH)-CH_2CH_3$ | $(2) \ \text{Isopropyl alcohol}$ | $(ii) \ \text{2,2-Dimethylpropan-1-ol}$ |
| $(C) \ CH_3-CH(OH)-CH_3$ | $(3) \ \text{Ethylene glycol}$ | $(iii) \ \text{Butan-2-ol}$ |
| $(D) \ (CH_3)_3C-CH_2OH$ | $(4) \ \text{Neopentyl alcohol}$ | $(iv) \ \text{Propan-2-ol}$ |
(A) The matching is as follows:
$(A) \ HO-CH_2-CH_2OH$ is Ethylene glycol $(3)$ and Ethane$-1,2-$diol $(i)$.
$(B) \ CH_3-CH(OH)-CH_2CH_3$ is sec-Butyl alcohol $(1)$ and Butan$-2-$ol $(iii)$.
$(C) \ CH_3-CH(OH)-CH_3$ is Isopropyl alcohol $(2)$ and Propan$-2-$ol $(iv)$.
$(D) \ (CH_3)_3C-CH_2OH$ is Neopentyl alcohol $(4)$ and $2,2-$Dimethylpropan$-1-$ol $(ii)$.
Therefore,the correct sequence is $(A$ $\rightarrow 3, i), (B$ $\rightarrow 1, iii), (C$ $\rightarrow 2, iv), (D$ $\rightarrow 4, ii)$.
$(A) \ HO-CH_2-CH_2OH$ is Ethylene glycol $(3)$ and Ethane$-1,2-$diol $(i)$.
$(B) \ CH_3-CH(OH)-CH_2CH_3$ is sec-Butyl alcohol $(1)$ and Butan$-2-$ol $(iii)$.
$(C) \ CH_3-CH(OH)-CH_3$ is Isopropyl alcohol $(2)$ and Propan$-2-$ol $(iv)$.
$(D) \ (CH_3)_3C-CH_2OH$ is Neopentyl alcohol $(4)$ and $2,2-$Dimethylpropan$-1-$ol $(ii)$.
Therefore,the correct sequence is $(A$ $\rightarrow 3, i), (B$ $\rightarrow 1, iii), (C$ $\rightarrow 2, iv), (D$ $\rightarrow 4, ii)$.
