Q. Compound A, $C_8H_{10}O$, is found to react with NaOI (produced by reacting Y with NaOH) and yields a yellow precipitate with characteristic smell. A and Y are respectively
A) $C_6H_5-CH(OH)-CH_3$ and $I_2$
B) $C_6H_5-CH_2-CH_2-OH$ and $I_2$
C) $H_3C-C_6H_4-CH_2-OH$ (p-methylbenzyl alcohol) and $I_2$
D) 2,4-dimethylphenol ($(CH_3)_2C_6H_3OH$) and $I_2$
Explanation
[Solution] 1-Phenylethanol has the $CH_3CH(OH)-$ group and gives the iodoform test (yellow $CHI_3$); NaOI is made from $I_2$ + NaOH. Answer (1).
