I'm having difficulty applying the cardio rule when comparing acids. Which one is more acidic etc
Any advice ? Or any other technique you guys use ?
Thanks
 
If they ask you to find the strongest acid, look for the molecule which is the least basic. If asked to find the weakest acid, look for the strongest base in the options.
 
Know common pka's. Know common trends and ask why's until it's all internalized. This may require resorting back to a textbook; textbooks can eloquently tell you what the why's are
