(a)
Interpretation:
From the given compounds, the compound with high regioselective ability towards addition of
Concept introduction:
Addition Reaction: It is defined as
The product of electrophilic addition reaction obtained by addition of electrophile to
Electrophile: Electrophiles are electron deficient compounds which accepts electrons from nucleophiles that results in bond formation.
Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.
Chemical reaction involves bond making and breaking of two or more reactants in order to attain products from the reactants.
Cation: The positively charged chemical species is referred as cation.
Regioselective reaction: They are reactions which contain more than one product which are actually molecules with same molecular formula but different in the way they are connected and among those products only one product is major.
