| Column-$I$ (Name) | Column-$II$ ($C-O$ bond length) and Column-$III$ ($C-O-H$ angle) |
|---|---|
| $A$. Methanol | $1$. $141 \ pm$,$i$. $109^o$ |
| $B$. Phenol | $2$. $136 \ pm$,$ii$. $111.7^o$ |
| $C$. Methoxymethane | $3$. $142 \ pm$,$iii$. $108.9^o$ |
(A) The structural properties of alcohols and ethers are as follows:
$A$. Methanol: The $C-O$ bond length is $142 \ pm$ $(3)$ and the $C-O-H$ bond angle is $108.9^o$ $(iii)$.
$B$. Phenol: The $C-O$ bond length is $136 \ pm$ $(2)$ and the $C-O-H$ bond angle is $109^o$ $(i)$.
$C$. Methoxymethane: The $C-O$ bond length is $141 \ pm$ $(1)$ and the $C-O-H$ bond angle is $111.7^o$ $(ii)$.
Therefore,the correct sequence is $A-3-iii, B-2-i, C-1-ii$.
$A$. Methanol: The $C-O$ bond length is $142 \ pm$ $(3)$ and the $C-O-H$ bond angle is $108.9^o$ $(iii)$.
$B$. Phenol: The $C-O$ bond length is $136 \ pm$ $(2)$ and the $C-O-H$ bond angle is $109^o$ $(i)$.
$C$. Methoxymethane: The $C-O$ bond length is $141 \ pm$ $(1)$ and the $C-O-H$ bond angle is $111.7^o$ $(ii)$.
Therefore,the correct sequence is $A-3-iii, B-2-i, C-1-ii$.
