Question

26. This is an example of SN2 reaction, so, doubling the concentration of nucleophile (NaI) will double the rate of reaction. Option B is correct

27. Greater the stability of carbocation formed, higher will be the rate of solvolysis. So, option A will be the right answer.

28. Option B is correct

29. Option D because it prduces tertiary carbocation (more stable carbocation)

30. Under acidic condition, opening occurs fron greater substituted site. So, option B will be the right option.

31. For endo thermic reaction, final product should have higher energy than reactant and for the first step to be rate limiting, activation energy of first step should be higher than the second. So, option D will be the rght option
