Question

In which of the following conversions, phosphorus pentachloride is used as the reagent?

• A. $C{H}_{3}C{H}_{2}OH\to C{H}_{3}C{H}_{2}Cl$
• B. $H_{2}C=C{H}_2\to C{H}_{3}C{H}_{2}Cl$
• C. $CH\equiv CH\to C{H}_2=CHCl$
• D. None of the above

Answer 1

The correct option is A $C{H}_{3}C{H}_{2}OH\to C{H}_{3}C{H}_{2}Cl$

When alcohol reacts with phosphorus pentachloride, alkyl halide is formed. Hence, the correct answer is option (a).

$C{H}_{3}C{H}_{2}OH+PC{l}_5\to C{H}_{3}C{H}_{2}Cl+POC{l}_3+HCl$
