Asked by | 09 Mar, 2008, 06:40: PM
Expert Answer
formic acid,benzoic acid,phenol, methanol,ethanol,water,ammonia, alkyne,alkene,alkyne
formic acid > benzoic acid > phenol > methanol > ethanol > alkyne > water > alkene > ammonia.
The H+ available is released in the given order and reacts accordingly.
Acidity depends on :
1. - I effect increases the acidic strength and + I effect decreases the strength.
2. More the Number of - I effect groups and nearer the distance from the COOH group will increase the +I effect.
Any factor which increases the -I effect and decreases the stearic hindrance will increase the +I effect.
