Concept explainers
(a)
Interpretation:
The reaction of free radical
Concept introduction:
The free radical is a molecule having unpaired electron in its molecular orbital. Due to the presence of unpaired electron the molecule become unstable and reactive. It can react with any another molecule to generate free radical.
(b)
Interpretation:
The comparison as a free-radical inhibitor of the isomer of ferulic acid,
Concept introduction:
The free radical is a molecule having unpaired electron in its molecular orbital. Due to the presence of unpaired electrons the molecule become unstable and reactive. The free radical inhibitor are the substances which inhibit the reaction.

- 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_forwardAs far back as the 16th century, South American Incas chewed the leaves of the coca bush, Erythroxylon coca, to combat fatigue. Chemical studies of Erythroxylon coca by Friedrich Wöhler in 1862 resulted in the discovery of cocaine, C17H21NO4, as the active component. Basic hydrolysis of cocaine leads to methanol, benzoic acid, and another compound called ecgonine, C9H15NO3. Oxidation of ecgonine with CrO3 yields a keto acid that readily loses CO2 on heating, giving tropinone. (a) What is a likely structure for the keto acid? (b) What is a likely structure for ecgonine, neglecting stereochemistry? (c) What is a likely structure for cocaine, neglecting stereochemistry?arrow_forwardHow do you decompose KHS2O3arrow_forward
