plz answer

Cl₂ + H₂O → HCl + [O]

So , there are two possibilities :

i) the double bond splits
or
ii) CCl₃^- is extracted out.

but the 2nd case is not favourable as a vinyl carbocation is formed.

thus , we go with first step and H⁺ attacks 2nd carbon as its stabilised by CCl₃^- and the other carbon is attacked by Cl^-.

thus product is : Cl₃-C-CH₂-CH₂-Cl

I think perhaps no. becoz if halohydrin reaction takes place , then Cl would be added to 2nd carbon and OH to 3rd carbon. thus :

i) there would be hindrance for a large group like Cl to be inserted

ii) lone pair - lone pair repulsion of four Cl groups

Hmm you're right!
