Question

The alcohol having molecular formula C4H9OH, when shaken with a mixture of anhydrous ZnCl2 and conc. HCl gives an oily layer product after five minutes. The alcohol is (A) H3C — (CH2)3 — OH (B) (CH3)2CH — CH2OH (C) (CH3)3C — OH (D) H3C — CH(OH) CH2 — CH3

Secondary alcohol, on reaction with anhydrous

Z n C l_{2}

and conc.

H Cl

(Lucas reagent) gives an oily layer product after five minuts.

H_{3} C - O H ∣ C H - C H_{2} C H_{3} Lucas reagent

oily layer
product (turbidity) after 5 min.

Q. The alcohol having molecular formula $C_{4} H_{9} O H$ , when shaken with a mixture of anhydrous $Z n C l_{2}$ and conc. $H Cl$ gives an oily layer product after five minutes. The alcohol is

$H_{3} C — (C H_{2})_{3} — O H$

$(C H_{3})_{2} C H — C H_{2} O H$

$(C H_{3})_{3} C — O H$

$H_{3} C — C H (O H) C H_{2} — C H_{3}$

Secondary alcohol, on reaction with anhydrous $Z n C l_{2}$ and conc. $H Cl$ (Lucas reagent) gives an oily layer product after five minuts.
$H_{3} C - O H ∣ C H - C H_{2} C H_{3} Lucas reagent$ oily layer
product (turbidity) after 5 min.
