Interpretation:
The reason that supports why
Concept Introduction:
Electronic effect:
Electron donating groups decreases acidity by inductive effect (withdrawal of electrons through a sigma bond). Electron withdrawal increases acidity. Electron-donating substituents destabilize a base, and decrease the strength of its conjugate acid; electron-withdrawing substituents stabilize a base, which increase the strength of its conjugate base.
Effect of delocalized electrons on
Due to Inductive effect, an anion is stabilized by a nearby electronegative atom. In the same way, electron delocalization also effective on stabilization of anion.
Rule: The strength of an acid depends on the stability of its conjugate base.

- Thioglycolic acid, HSCH2CO2H, a substance used in depilatory agents (hair removers) has pKa = 3.42. What is the percent dissociation of thioglycolic acid in a buffer solution at pH = 3.0?arrow_forwardThe following pKa values have been measured. Explain why a hydroxyl group in the para position decreases the acidity while a hydroxyl group in the meta position increases the acidity.arrow_forwardAlthough codeine occurs in low concentration in the opium poppy, most of the codeine used in medicine is prepared from morphine (the principal component of opium) by the following reaction. Explain why selective methylation occurs at only one OH in morphine to give codeine. Codeine is a less potent and less addictive analgesic than morphine. но. CH,0. [1 кон H [2] CH3I H.
