`underset("Specific rotation" = +50^(@))(Ph-CH(OH)CH_(3)) overset(SOCl_(2))(rarr) underset(Cl)underset(|)(PhCH) - CH_(3)` What si the specific rotation of the product?A. `+50^(@)`B. `+60^(@)`C. `-60^(@)`D. Zero

Answer» Correct Answer - `b`
It is an example of `SN^(1)` reaction in which retention takes place. So, if reactant specific rotation is positive, it should be positive for the product also, but of different value since the reactant and product are different.
