Consider the following reactions:
I.Me3C−Cl⊖OH−−→Me3C−OHII.F3C−CH|Me−Cl⊖OH−−→F3C−CH|Me−OHIII.Me3C−Cl90%D2O+10%ether−−−−−−−−−−−−→Me3C−ODIV.Me3C−Cl90%H2O+10%ether−−−−−−−−−−−−→Me3C−OH
Which of the following statements are correct?
Reaction (IV) is faster than (III).
i. In (II), carbocation is destabilised by stronger -I effect of three F atoms, and thus solvolysis of (II) is slower than that of (I).
ii. D -bonds are not as stabilising as H-bonds. So reaction (IV) is faster than (III).
