1. CH2=CH-CH3 inpresence of SO2Cl2 (UV light) product..??

2. (CH3)3CH +Cl2 undergo photo halogenation product..??

3. 1-propyne react with HCl product is..??

plzz xplain.

1 SO2Cl2 results in allylic chlorination like NBS so product is CH2=CH-CH2Cl

2 photo halogentaion takes place on the site with the most stable carbocation hence (CH3)-C-Cl will be major product with many other products in minor 

3 reaction takes place acc to markonikov rule negative part of attacking molecule goes to C with less hydrogen (explanation lies in its mechanism) product formed is CH2=C(Cl)-CH3

2-it follows the free radical mechanism,there are two positioins of free radical formation so products are (CH3)3Cl &          (CH3)2CHCH2Cl.

But in the ans. In 2nd ques. (CH3)3C-Cl is not the major product..
