The correct order of increasing acid strength of the compounds
(I) \[C{{H}_{3}}C{{O}_{2}}H\]
(II) \[MeOC{{H}_{2}}C{{O}_{2}}H\]
(III) \[C{{F}_{3}}C{{O}_{2}}H\]
(IV)
AIEEE Solved Paper-2006
A)II < IV < I < III
B)IV < I < III < II
C)IV < I < II < III
D)I < IV < III < II
Correct Answer:
C
Solution :
\[-l\] effect increases acidity. F \[+l\] effect decreases acidity. \[-C{{F}_{3}}\]exerting more \[-\,l\] effect than\[-\text{ }OMe\] \[M{{e}_{2}}CH-\]exerting more \[+\,l\] effect than\[C{{H}_{3}}\]
