F-CH3CHC02H Cl -ch2ch2co2h Identify the most acidic carboxylic acid.FCH2COOH CICH2COOH BrCH2COOH ICH2COOH CH3COOH Draw a resonance contributor for H0C02 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all hydrogen atoms. Include all lone pairs of electrons. Show the formal charges of all nonhydrogen atoms in the correct structure Choose the resonance hybrid for H0C02 Arrange in order of increasing acid strength (weakest acid first, etc.) Rank the following bases in order of basicity, from strongest to weakest. (Hint: consider how resonance and electronegativity will influence the stability of the conjugate acid.)Rank from strongest to weakest. To rank items as equivalent, overlap them.Rank the following organic acids in order of acidity, from strongest to weakest. (Hint: Consider how resonance and inductive effects will influence the stability of the conjugate base.)Rank from strongest to weakest. To rank items as equivalent, overlap them.
Explanation / Answer
1) B
2)A
3)D
4)A
5) Basicity of bases strongest to weakest : NaOH > CH3CHNH2 > CH3CHOH > CH3CONH2
6)
4>1>3>2
More electronegative atom if present then more acidic
