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

- For each pair of compounds: [1] Which indicated H is more acidic? [2] Draw the conjugate base of each acid. [3] Which conjugate base is stronger?arrow_forwardWhich compound is the strongest base?arrow_forwardDraw DMAP in bond line format with all lone pairs, as needed. Draw the resonance structures, and circle the resonance form that best explains why DMAP's ring nitrogen is so basic. Briefly explain why DMAP's ring nitrogen is so basic by considering the resonance form you circled and what makes an atom basic.arrow_forward
- Rank the following compounds from strongest acid to weakest acid:arrow_forwardMolecule A’s most acidic hydrogen has a pka of 4.1. Point out the most acidic hydrogen and draw it’s conjugate basearrow_forwardA) for each compound show its conjugate base. lone pairs have been left out. B) rank the conjugate base in the order you would predict, from most to least stable. C) rank the original compounds in order, from strongest to weakest acid.arrow_forward
