Inductive effects - correct answer The way in which electronegative atoms polarise
electron density in the single bond framework of a molecule
-I electron withdrawing effect - correct answer atoms that pull electrons away from
the carbon that they are bonded to. more electronegative than carbon
+I electron donating effect - correct answer carbon is pulling the electrons closer to
itself as the atom it is bonded to is less electronegative
Reactivity - correct answer The movement of electron density in order to break
weak bonds and form new stronger bonds. This is based on controllable and predictable electronic
effects.
Mesomeric effects - correct answer The movement of electron density within the
double bond/lone pair system of a molecule by resonance conjugation.
Rules of Mechanism - correct answer Rule 1: The electron must start from
somewhere good
(negative charge > lone pair > double bond > single bond)
Rule 2: The electron flow must move towards something
(+ve charge on a C or an H+ > atom adjacent to +ve charge on a heteroatom > partially positive charge)
Rule 3: The electron flow must end up somewhere decent
MAKE SURE TO CONSERVE THE CHARGE
Nucleophile (Nu-) - correct answer An electron rich species that will react with C+
