Explain why reaction of HCl with CF(2)CH...

Explain why reaction of `HCl` with `CF_(2)CH=CH_(2)` proceeds according to antiomarkownikov's rule.

Text Solution

Verified by Experts


Fluorine (F) being a highly electronegative element has a strong `-I` effect. Therefore, when `H^(+)` form acid (electrophile) attacks the substrate, a primary carbocation formed. This reacts with the anion to give the desired product.
