(a)
Interpretation:
The given substrates should be determined that whether they favor
Concept introduction:
Carbocation: it is carbon ion that bears a positive charge on it.
Carbocation stability order:
Carbo-cation Rearrangement:
Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.
(b)
Concept introduction:
Structure of the substrate plays an major role in the reactivity of
Leaving group: it is a fragment that leaves the chemical compound with pair of electrons in a heterolytic bond cleavage. The
Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation.
Nucleophilic nature depends on the negative charge present in the molecule, the solvent in which it present and the electronegativity of the atom.
(c)
Concept introduction:
Factors that favors both
Secondary substrates, benzylic and allylic substrates undergoes via both the reaction mechanism.
Secondary substrates being in the middle between tertiary and primary they will undergo via both the mechanisms.
Allylic halides results in secondary substrate as halide group leaves and it favors
Benzylic halides also react via both mechanisms since it forms sterically unhindered secondary substrate and more stable resonance stabilized cation.

(e)
Concept introduction:
Substrates that do not undergo in either of the two given mechanism are vinyl and aryl substrates. They do not follow
Vinyl group: It is
Aryl group: It is functional group derived from
