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
