$A$ and $B$ are :
| $pH$ at Isoelectric point | |
| $(Amino acid)_I$ | $6$ |
| $(Amino acid)_{II}$ | $9.8$ |
| $(Amino acid)_{III}$ | $3.9$ |
$(Amino acid)_{II}$ is ____ ?
Assertion $A$: $\mathrm{pK}_{\mathrm{a}}$ value of phenol is $10.0$ while that of ethanol is $15.9$.
Reason $R$: Ethanol is stronger acid than phenol.In the light of the above statements, choose the correct answer from the options given below:
${C_6}{H_5} - O - C{H_2} - C{H_3}\xrightarrow{{Excess\,HI/\Delta }}\left[ X \right] + \left[ Y \right]$
$[X]$ and $[Y]$ will respectively be
