Question

arrange according to their increasing order of acidic strength

Answer 1

4231 this is the ans

Answer 2

Answer:

Explanation:

first remove hydrogen from more electronegative atom

- charge is stabilised by -i effect

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

if you see compound 2 in a

it is more electropositivity so 2 has more acidic strength than others

then hcooh after chcooh and ch3cooh

so order is

ccl3cooh>hcooh>chcooh>ch3cooh

lets do the same for b

remove hydrogen from electronegative atom

bulky substituents inversely proportional to acidic strength

so 1 has more than two compounds that are 2 and 3

compound3 has less electronegativity so it has more acidic strength than 2

1>3>2

ch3cooh>(ch3)2ccooh>(ch3)2chcooh
