Question

How Alcohol can be converted into alkyl halide?

Answer 1

Preparing Alcohols

The oxygen will receive hydrogen from the acid, forming H2 O+. Now, the leaving group would no longer be OH-, but instead, it will be water: H2 O.

Any strong acid can be used to form H2 O+, but it is most effective when we use a halide acid (HX, such as HI, HBr, or HCl), because then the halide is ready for the SN2 or SN1 reaction.

Answer 2

ch3-oh + hcl = ch3-cl +h2o

ch3-oh + pcl5= ch3-cl + pocl3 +hcl
