Question

The reaction of $SOC{l}_2$ on alkanols to form alkyl chlorides gives good yields because:

• A. alkyl chlorides are immiscible with $SOC{l}_2$
• B. the other products of the reaction are gaseous and escape out
• C. alcohol and $SOC{l}_2$ are soluble in water
• D. the reaction does not occurs via intermediate formation of an alkyl chlorosulphite

Answer 1

Answer: (B)

the other products of the reaction are gaseous and escape out

The reaction of $SOC{l}_2$ on alkanols to form alkyl chlorides gives good yields because the other products of the reaction are gaseous and escape out.
For example, ethanol reacts with thionyl chloride to form chloroethane. The gaseous byproducts are sulphur dioxide and hydrogen chloride.
