In which one of the following conversions phosphorus pentachloride is used as a reagent

Answer»

`H_(2)C=CH_(2)toCH_(3)CH_(2)Cl`
`H_(3)C-O-CH_(3)toCH_(3)Cl`
`CH_(3)CH_(2)OHtoCH_(3)CH_(2)Cl`
`HC-=CHtoCH_(2)=CHCl`

Solution :`CH_(3)-O-CH_(3)+PCl_(5)to2CH_(3)Cl+POCl_(3)`
`CH_(3)CH_(2)OH+PCl_(5)toCH_(3)CH_(2)Cl+HCl+POCl_(3)`
So, both reaction carried out by `PCl_(5)`.
