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 |
