Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

see fluorine is electron withdrawing in nature(due to e vity)
so there are 3 fluorine per carbon indirectly attached to
C---OH so cause this bond more polar furthur causin
O~H bond more polar
in first case 9 f
in second 6
so addn effect of 3 f
so 1st one more acidic

TAKE INTO CONSIDERATION THE 3D PICTURE DONT U SEE EXTENSIVE HYDROGEN BONDING IN TWO ?
SEE THE F-F ATOM REPULSION IS HIGHER IN TWO FORCING THE CF3 TO GO MORE TOWARDS THE OH GREOUP INCREASING THE SYTRENGTH OF HYDROGEN BOND
BUT IN ONE THE CF3 ARE FEE TO ORIENT SUCH THAT H BONDING IS NOT POSSIBLE .
F-F REPULSION IS MORE THAN F-O REPULSION COZ F IS MORE E.N THAN O
