Question

Please rank the following acids from least to greatest strength:

formic

acetic

methanoic

propanoic

lactic

please also explain how to determine acid strength of these molecules without a Ka

science chemistry

Answer 1

Answer #1

For acidity of any bronset acid only see how much stable it's conjugate base

More stable conjugate base more acidic strength of acid

Acidity order of above acid-

Formic acid> Lactic acid>Acitic acid>propanoic acid.

OH group if in conjugation then behave as+M group but if not in conjunction then work as -i effect.

In lactic acid OH group behave as - I effect because it is not in conjunction with corboxylic group.
