second one check the hybr. of carbon to which cooh is attached

bcoz in third it is pur sp2 hybrd. but in case of second due to resonance it is between sp and sp2.....

rest sp3

which has more electronegative power?

second one so it ll make carbon more acidic...........

the souce that i have says that last one is correct...

typo error in the last one, the group attached should be CH₂COOH

2 nd one only.... coz the electron density will be pulled towards carbon atom.....sp2 hybridised

Answer will be second one as benzene ring has some -I effect which pulls the electron density towards itself and hence electron density on the H+ gets decreased. So, that it can be easily released and gives acidic character.

it'll be second one......coz the anion formed after the removal of H+ is more stable as cmpared 2 others.this is bcoz benzene ring here will show -M effect n not -I effect(@ SAGAR) n due to dis it wil reduce the electron charge density on COO^- group.....

3rd n 4th r even not corrctly structured........
