Concept explainers
a)
Interpretation:
The most acidic hydrogens present in CH3CH2CHO are to be identified.
Concept introduction:
The hydrogens present on carbons adjacent to electron withdrawing groups like carbonyl, nitrile etc. and electron attracting electronegative atoms like N, O and F are acidic and can be readily removed as protons.
Carboxyl proton is highly acidic as the carboxylate anion can be stabilized by resonance.
To identify:
The most acidic hydrogens present in CH3CH2CHO.
b)
Interpretation:
The most acidic hydrogens present in (CH3)3CCOCH3 are to be identified.
Concept introduction:
The hydrogens present on carbons adjacent to electron withdrawing groups like carbonyl, nitrile etc. and electron attracting electronegative atoms like N, O and F are acidic and can be readily removed as protons.
Carboxyl proton is highly acidic as the carboxylate anion can be stabilized by resonance.
To identify:
The most acidic hydrogens present in (CH3)3CCOCH3.
c)
Interpretation:
The most acidic hydrogens present in CH3COOH are to be identified.
Concept introduction:
The hydrogens present on carbons adjacent to electron withdrawing groups like carbonyl, nitrile etc. and electron attracting electronegative atoms like N, O and F are acidic and can be readily removed as protons.
