318030 The intermediate carbocation formed in the reactions of \(\mathrm{HI}, \mathrm{HBr}\) and \(\mathrm{HCl}\) with propene is the same and the bond energy of \(\mathrm{HCl}, \mathrm{HBr}\) and \(\mathrm{HI}\) is \(430.5 \mathrm{~kJ} \mathrm{~mol}^{-1}, 363.7 \mathrm{~kJ} \mathrm{~mol}^{-1}\) and 296.8 \(\mathrm{kJ} \mathrm{mol}^{-1}\) respectively. What will be the order of reactivity of these halogen acids?

1 \(\mathrm{HI}>\mathrm{HBr}>\mathrm{HCl}\)
2 \(\mathrm{HBr}>\mathrm{HI}>\mathrm{HCl}\)
3 \(\mathrm{HCl}>\mathrm{HBr}>\mathrm{HI}\)
4 \(\mathrm{HI}>\mathrm{HBr} < \mathrm{HCl}\)

318031 The reaction of propene with \(\mathrm{HOCl}\left(\mathrm{Cl}_{2}+\mathrm{H}_{2} \mathrm{O}\right)\) proceeds through the intermediate:

1 \(\mathrm{CH}_{3}-\mathrm{CH}(\mathrm{OH})-\mathrm{CH}_{3}\)
2 \(\mathrm{CH}_{3}-\mathrm{CHCl}-\mathrm{CH}_{2}^{+}\)
3 \(\mathrm{CH}_{3}-\mathrm{CH}^{+}-\mathrm{CH}_{2}-\mathrm{OH}\)
4 \(\mathrm{CH}_{3}-\mathrm{CH}^{+}-\mathrm{CH}_{2}-\mathrm{Cl}\)

318033 The addition of \(\mathrm{HI}\) in the presence of peroxide catalyst does not follow anti-Markovnikov's rule because

1 \(\mathrm{HI}\) is a strong reducing agent
2 H-I bond is too strong to be broken homolytically
3 I atom combines with \(\mathrm{H}\) atom to give back \(\mathrm{HI}\)
4 Iodine atom is not reactive enough to add across a double bond
