Question

Reaction of alcohol with SOCl2 is ___________? *
• SN1 reaction
• SN2 reaction
• Intramolecular Nucleophilic substitution reaction (SNi)
• SNAr​

Answer 1

Answer:

you take an alcohol and add thionyl chloride, it will be converted into an alkyl chloride. The byproducts here are hydrochloric acid (HCl) and sulfur dioxide (SO2

Answer 2

The reaction of alcohol with $SOCl2$ is a $SN2$ reaction.

Explanation:

• The conversion of alcohols to alkyl halides is carried out through a substitution reaction and that specifically, an $SN2$ mechanism.
• At the first step, there is an attack of the oxygen upon the sulfur $SOCl2$, which results in the displacement of chloride ions.
• There is the conversion of alcohol to alkyl halides and this is done with the help of thionyl chloride.
• This reaction is a $SN2$ reaction where an attack of the oxygen upon the sulfur of SOCl2, takes place which results in the displacement of chloride ions.
• Here converting the alcohol into a good leaving group is done.
• The next step carries chloride ion to attack the carbon in $SN2$ the mechanism which results in cleavage of the C–O bond with inversion of configuration.
• The $HOSCl$ breaks down into HCl and sulfur dioxide gas.
