Me_(3)C CH_(2)COOH is more acidic than Me_(3)SiCH_(2)COOH. |
Answer» Solution :SI (E.N.=1.8) is more electropositive than C (E.N.=2.5), therefore, `Me_(3)Si` (trimethylsilyl group) has greater +I-effect than that of `Me_(3)C` (t-butyl group). As a result, `Me_(3)Ci` intesifies the -ve charge on the carboxylate ion relative to t-butyl group and HENCE `Me_(3)C CH_(2)COOH` is a stronger acid than `Me_(3)SiCH_(2)COOH`.  .
