Question

Ethanol is converted into ethlyl chloride by reacting with

• A. $C{l}_2$
• B. $SOC{l}_2$
• C. $HCl$
• D. $NaCl$

Answer 1

The correct option is B $SOC{l}_2$

$C_2{H}_{5}OH+SOC{l}_2\to C_2{H}_{5}Cl+S{O}_2\uparrow +HCl$
This is a good method for the preparation ​of alkyl halide​. By-products of this reaction are gaseous in nature.
This reaction follows $S{N}_i$ mechanism.​ Hence, the correct answer will be option (b).
