ethyl alcohol

acid ; acetic acid

base ethyl alcohol

both w.r.t each other

reason think of resonance in acid and relative unstability of 1^o carbocation in the base

pka-ethyl alcohol- 15.9       and  for acetic acid -4.76    so -<ethyl alcohol>

it is ethyl alcohol     since see the pic  since the powerfull electronegative atom oxygen try to attract the electron pair towards it  since there are two oxygen atoms hence the electron density near the carbon is less   and also moreover the due to both oxygen atoms reduces electron density  the  the carbon nucleus also try  to attract the electrons hence there would  be less  some wat less electron density on the oxygen atom  than the chain which contain single oxygen atom hence relatively less density so the electron density on the oxygen reduces rlatively   hence it can easily loose hydrogen hence less basic

For Acetic Acid:

CH₃COOH -> CH₃COO^- + H⁺

THE ACETATE ION ON THE RHS OF THE ABOVE EQUATION: IS RESONANCE STABILISED. HENCE, THE RHS OF THE ABPVE EQUATION IS STABLE, HENCE THE REACTION PROCEED IN FORWARD DIRECTION MORE. THEREFORE H⁺ ION CONCENTRATION IN THE SOLUTION INCREASES. BUT FOR THE ETHYL ALCOHOL, THERE IS NO RESONANCE STABILISATION FOR THE ETHOXY ION (CH₃CH₂O^- ). HENCE ITS NOT SO STABLE, RATHER THAN MORE REACTIVE DUE TO +I EFFECT OF ETHYL GROUP.

SO, ACETIC ACID IS MORE ACIDIC IN NATURE THAN ETHYL ALCOHOL.

GOI IT?...

Basicity of ethyl alcohol = -1.9 and acidity of acetic acid = + 4. 76 , thus ethyl alcohol is more basic than acetic acid.
