Predict all order of reactivity of the following compounds in dehydrohalogenation. a,. I. CH_(3)CH_(2)CH_(2)CH_(2)Cl II. (CH_(3))_(2)CHCH_(2)Cl III. (CH_(3))_(2)CH - CH_(2)Br IV. CH_(3)CH(Br)CH_(2)CH_(3) V. (CH_(3))_(3) C - Br b. I. CH_(3)CH(Br)CH_(3) II. CH_(3)CH_(2)CH_(2)Br III. (CH_(3))_(2) CH - CH_(2) Br IV. (CH_(3))_(3)C - CH_(2) Br |
Answer» Solution :  Ease FO dehdrohalogenation is DUE to the formation of carbocation and the stability of carbocation is `3^(@) gt 2^(@) gt 1^(@)`, and CASE of fornation of carbocation is `(R-1) gt (R-Br) gt (R-Cl)` So the order of dehydrogenation is `(V)gt (III) gt (II) gt (IV) gt (I)`. |
