Consider the following reactions:
Which of the following statements are correct?
Reaction (II) is faster than (I).
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).
