Solution:Answer:(b) 2-chloro-3,3-dimethylpentaneExplanation:A rearrangement occurs in a SN1 reaction when the carbocation is formed. More substituted carbocations are more stable because of the electron-donating effect of alkyl groups and the hyperconjugation.An alkyl halide with a carbon more substituted than the carbon where is the C-X bond, is most likely to undergo rearrangement.The SN1 reaction goes much more readily in polar solvents that stabilize ions. The rate-determining step forms two ions, and ionization is taking place in the transition state. Polar solvents solvate these ions by an interaction of the solventÕs dipole moment with the charge of the ion.

The answer is same for the SN 1 reaction as for as for the SN 2 reaction. The weaker the bases, the less lightly it is bonded to the carbon and the easier it is to break the C – halogen bond.

(i) (CH3)3C—F (ii) (CH3)3C—Cl (iii) (CH3)3C—Br (iv) (CH3)3C—I. Solution:• Alkyl halides have the general formula RX, in which R is an alkyl group or substituted alkyl group, and X represents the halogen atom (X=F, Cl, Br). • The reactions that are characteristic of the family are the ones that occur at the halogen atom. • In alkyl halides, the functional group is the halogen atom.

Answer : The reaction of alkyl halides with aqueous KOH is nucleophilic substitution reaction. The reaction can undergo either by S N 1 mechanism or S N 2 mechanism. Under S N 1 condition : In S N 1 reaction, the reactivity increases as the stability of intermediate carbocation increases.

Hint: Alkyl halides are a class of organic compounds in which an alkyl group is attached to a halogen atom. The alkyl group is made of carbon and hydrogen atoms. Examples of alkyl groups are methyl, ethyl, isobutyl and tert-butyl. \[{S_N}1\] reaction is a type of substitution whose rate is dependent on the formation of one species i.e. carbocation.
