(a) Interpretation: Whether the given substituent exhibits an electron-withdrawing or an electron-donating inductive effect is to be identified. Concept introduction: The atoms which are more electronegative than carbon pull charge density away from carbon and exhibit an electron-withdrawing inductive effect. Alkyl groups donate electron density, thus exhibit an electron donation inductive effect.
