1.	Explain the terms inductive and electromeric effects. Which electron displacement effect explains the following correct order of the acidity of the carboxylic acids ? (a) CH_(3)COOH gt Cl_(2)CHCOOH gt ClCH_(2)COOH (b) CH_(3)CH_(2)COOH gt (CH_(3))_(2)CHCOOH gt (CH_(3))_(3)COOH
Answer» Solution :For the details of the effects, Section 12.22 & Section 12.23 (a) The order of acidity is explained by `-I` EFFECT of the CHLORINE atoms. Greater the magnitude of `-I` effect, EASIER will be the release of `H^(+)` from `O-H` bond and stringer will be acid. (b) The order of acidity is explained by `+ I` effect of alkyl groups. As the number of alkyl groups increases, the magnitude of `+ I` effect also increases. As a result, the release of `H^(+)` from `O-H` bond becomes more and more DIFFICULT and acidic strength decreases.
