  4. DII IV I

Correct answer

B. III IV IV

Step-by-step solution

(A) Addition of HI takes place by the formation of 1^ and 2^ carbonium ion. 2^ carbonium ion being more stable will form major product, i.e. 2-iodopropane. (B) The reaction of bromine with 1-phenylethane proceed with formation of free radical. 2^ free radical being more stable than 1^ free radical, will form the product as 1-bromo-1-phenylethane. (C) Reaction of HBr to an alkene follows Markownikoff rule. So, the product will be 1-bromo-1-phenylethane. Note : Markownikoff's rule states that, electron rich component
