1.	In the presence of a peroxide, hydrogen chloride and hydrogen iodode do not undergo anti-Markovnikov's addition to alkenes because
Answer» both are highly ionic one is OXIDIZING and the other is reducing one of the steps is ENDOTHERMIC in both the cases all the steps is endothermic in both the cases Solution :`RO-ORrarr2RO^(.)OVERSET(H-X)(rarr)ROH+X^(.)` `(i) X^(.)+CH_(2)=CH-RrarrXCH_(2)overset(.)(C )HR` `(ii) XCH_(2)CHR+H-Xrarr XCH_(2)CH_(2)R+X^(.)` For `HCl`, STEP `(i)` is exothermic while step `(ii)` is endothermic. For `HI`, step `(i)` is endothermic while step `(ii)` is exothermic.
