Is H3CC(=O)CH2CH3 more likely to act as a Lewis Acid or Lewis Base? Explain your choice.
Same for HCO2H (formic acid)
The Attempt at a Solution
Since a Lewis Base donates electron pairs, and the oxygen in H3CC(=O)CH2CH3 has two lone pairs, I reasoned that H3CC(=O)CH2CH3 is a Lewis Base.
I know HCO2H should be a Lewis Acid because it is formic acid, but I don't know how the molecule would accept an electron pair.
