Alkaline hydrolysis of which among the following compounds leads to the formation of a racemate ?

Options

A. 1-bromo-1- phenylethane
B. 1-chloro-3-methylbutane
C. Bromoethane
D. 1-chloropropane

Answer

A

Explanation

`RX + KOH overset("alkaline")underset("hydrolysis")(to) ROH + KX`

Due to production of compound having chiral carbon , this hydrolysis will lead to the formation of a recemate

(c) `underset("Bromo ethane")(CH_(3)CH_(2)Br ) + KOH to underset("ethanol")(CH_(3)CH_(2))OH + K Br`
(d) `underset(1- "chloro propane")(CH_(3)CH_(2)CH_(2)Cl) + KOH to CH_(3) underset("Propanol")(CH_(3)CH_(2))OH + KCl`
Since , products of (b) , (c) and (d) do not have any chiral carbon atoms , so these cannot form a racemate .
