Question
Identify the strongest acid amongst the followings:
- Chloroacetic acid
- Acetic acid
- Trichloroacetic acid
- Dichloroaceticacid
Solution
(c) Trichloroacetic acid
As the number of chlorine atoms increases, the electronegativity of that end of the molecule increases and the molecule adopts a progressively more ionic character (e.g. density, boiling point and acidity).

Which one of the following acids does not exhibit optical isomerism?
\[\ce{CH3CH2COOH ->[Cl2][red P] A ->[alc. KOH] B}\]. What is B?
An aromatic carboxylic acid [A], which readily sublimes on heating, produces compound [B] on treatment with PCl5, Compound [B], when reduced in the presence of Pd catalyst over BaSO4 poisoned by sulphur in xylene solution, gives compound [C]. When compound [C] is condensed in the presence of alcoholic KCN, it gives compound [D] (Molecular formula of compound [D] is C14H12O2)
