The acid strength of substituted carboxylic acids is known to be dependent on the nature and position ofthe substituent. In the following examples, an attempt has been made to arrange the acids in order of acid strength, the strongest first. One of the series is incorrect-which one? (a) CH,.CH,CH(CI).COOH> CH,CH(C).CH,COOH> CHCH,.CH,.COOH (b) NO,.CH,.COOH > HOCH,.COOH> CH,.COOH (c) CI,C.COOH> BrCH,.COOH> FCH,.COOH (d) CH,.COOH> CH,.CH,.COOH> (CH),C.COOH Arranae 1he oiven carbon acids in the increasing order of acidic strength
