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?

Solution) 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
