Factors affecting pKa 1

Weak A-H bonds lead to stronger acids

Factors affecting pKa 2

Stability of A- due to charge beeing on electronegative atom

Factors affecting pKa 3

Delocalisation of -ve charge makes A- more stable so HA more acidic

Factors affecting pKa 4

Inductive effects if electronegative atoms are attached to A- it will draw -ve charge away and stabilise A-. Also an electron donating group Me/Et will push electrons towards A- making the charge more -ve and destabilising A-.

Factors affecting pKa 5

An SP orbital is lower in energy as it contains more S character so the conjugate base would be more stable so would be more acidic
