Concept explainers
(a)
Interpretation: The stronger acid of the given compounds has to be found.
Concept introduction:
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Electronegative of hybrid orbitals depends upon the % s character. Hence more the s character more the electronegativity.
The acidity depends upon the electronegativity of an atom. More the electronegativity more the acidity.
The oxygen is more electronegative. Therefore, it attracts a shared pair of electron pair of

- Summarize the relationship between pKa and acid strength by completing the following sentences: a. The higher the pKa of an acid, the stronger or weaker the acid. b. The lower the pKa of an acid, the stronger or weaker the acid.arrow_forwardWhich one is more acidic in each pair? And why?arrow_forwardWhich acid is stronger, propanoate or lactic acid, and why? O lactic acid, because the K, of lactic acid is smaller than the K, of propanoic acid O propanoic acid, because the Ka of propanoate is smaller than the Ką of lactic acid lactic acid, because the Ka of lactic acid is larger than the Ka of propanoic acid O propanoic acid, because the K, of propanoic acid is larger than the Ka of lactic acidarrow_forward
