Concept explainers
(a)
Interpretation: Mechanism and curved arrow pattern of the reaction should be identified.
Concept introduction:
Nucleophiles (positive-charge loving): A nucleophile is a more reactant species that affords a pair of electrons to the electrophile or electrophilic center and forms a new covalent bond.
The carbon or other hetero atom in a molecule which is bearing negative charge or lone pair of electron is called as nucleophiles.
Nucleophilic addition: electron rich nucleophile attacks the positive or partially positive charge of an atom and forms the product is called nucleophilic addition reaction.
(b)
Interpretation:
Mechanism and curved arrow pattern of the reaction should be identified.
Concept introduction:
Electrophile (negative-charge loving): A molecule or ion that accepts a pair of electrons to make a new covalent bond is called an electrophile.
Electrophiles are neutral or positively charged species, having vacant orbitals and attracted electron towards itself.
Electrophilic substitution reactions: Electrophilic
