Question

Hcooh , ch3cooh, ch3ch2ch(cl)cooh, clch2ch2ch2cooh which is strongest acid

Answer 1

jyoti listen if u wanna know I refer u to study +R effect concept of chemistry it says that alkyl group has e donating nature in above 4 has big alkyl group means more +R effect that of three groups where hcooh has less +R effect due to h present in it
2...reason is polar nature of oh bond in cooh as o is electronegative in nature it will attract Carbon atom which has high e density over it due to alkyl R effect thus in case where o easily gets e from carbon atom it's bond strength with oh decreases as a result removal of h+from oh becomes difficult as it will allow whole h atom to leave from it becomes it's necessity is fulfilled by C atom due to presence of bulky alkyl group so hcooh is strongest acid as h will do not share e with C atom and polarity between oh will not effect nd thus removal of h+ is easy as it will allow h to leave but not it's e due to high electronegative nature act as strong acid...

Answer 2

Answer:

option c

Explanation:

ch3ch2ch(cl)cooh is strongest acid due to more -I effect

we know that as -I effect increase acidic character also increase
