Arrange the following alkenes towards order of increasing reactivity in cationic polymerization. H_(2)C=CHCH_(3),H_(2)C=CHCI,H_(2)C=CHC_(6)H_(5),H_(2)C=CHCO_(2)CH_(3). |

Answer» Solution :Reactivity TOWARDS cationic polymerization increases as the stability of the inmtermediate carbocation increases. Since the stability of the intermediate carbocations increases in the order : `H_(3)C-overset(+)(CH)-CO_(2)CH_(3)ltH_(3)C-overset(+)(CH)-CILT CH_(3)-overset(+)(CH)-CH_(3)lt H_(3)C-overset(+)(CH)-C_(6)H_(5)` therefore, reactivity of the corresponding alkenes towards cationic polymerization increases in the same order : `H_(2)C=CHCO_(2)CH_(3)lt H_(2)C=CHCI lt H_(2)C=CHCH_(3)lt CH_(2)=CHC_(6)H_(5)` . |
