Consider the compound and arrange X,Y, Z in order of increasing acid strengths .A. `X gt Z gt Y`B. `Z lt X lt Y`C. `X gt Y gt Z`D. `Z gt X gt Y`

Answer» Correct Answer - A
Carboxylic acids are stronger acids than `-NH_(3)^(+)` , therefore X is the strongest acid. Since -COOH has -I effect which decreases with distance , therefore, effect is more pronounced on Z than on Y. As a result Z is more acidic than Y. Therefore, overall order of increasing acid strength is `X gt Z gt Y`.
