Question

Can you explain basicity, and what makes a molecule a stronger base? How do electron withdrawing groups such as sulfur or phosphorus affect it?

Answer 1

there are mainly two factors which influence the strength of a base those are

ease of the molecule to  donate electron and the stability of ions being formed.

so the thing can be explained by the inductive effect. the inductive effect is the electron effect due to the polarisation of sigma bond with in amolecule or ion.this is due to the electronegetivity difference between atoms at either end of the bond.

there are mainly 2 inductive effect that is +I or positive inductive effect and-I or negative inductive effect.

the basic nature canbe explained by +I effect.

the group such as  sulfur or phosphorus attach to the molecule increases the overall electron density on the molecule and hence the molecule able to donate electron hence become basic in nature.
