Question

Acidity strength of butanoic acid,1-chloro butanoicacid,2-chloro butanoic acid

Answer 1

anything that displaces the equilibrium to the right will result in increased acidity. In turn, this is related to the stability of RCOO- . organic compounds tend to prefer being neutral but if charged then ways to distribute the charge are sought

Answer 2

Answer:

Explanation:

first draw structures of all

if you see in all these compounds last two carbons starting from carboxylic acid

so propanoic is taken as a system

and then remove hydrogen from oxygen of propanoic acid

we know that negative charge is stabilised by -i effect

for more -i effect the central atom should be more electropositive / less electronegative

in ch3coo ,ch3coocl + , ch2clcoo

second one is more stable than two as it is electropositive

after third is stable because chlorine is attached to that

so order is

2>3>1
