Question

Acetaldehyde, Ethanol, Acetic Acid

- Are all the hydrogens in acetaldehyde equally acidic? Explain.

- What molecule is likely to interact with a positively charged species? Explain.

Answer 1

No all the hydrogen of acetaldehyde are not equally acidic the Alfa hydrogen atom are more acidic than the hydrogen atom join with carbonyl carbon atom because after releasing Alfa H atom the negetive charge is resonance with carbonyl carbon atom

The carboxylic acid is interact with positive charge species because after accept proton the -0H group becomes a good leaving group and after releasing leaving group the positive charge of the carbon atom stabilised by the +R effect of oxygen atomwhile in alchol after releasing leaving group the positively charge carbon atom stabilised only by +I effect of methyl group and in aldehyde carbonyl does not react very good with positive chargr species
