Asolution of ethanol differs from a solution of propanoic acid in that the solution of propanoic

A solution of Proponic acid is more acidic than ethanol

The Boiling point of propanoic acid is more than ethanol

Explanation:

1.The boiling point of  propanoic acid  is more than the boiling point of ethanol because of H- bonding.

The electronegative O atom having the lone pair attracts the H of other molecule. Hence the molecules of ethanol show strong intermolecular H-Bonding.

CH3CH2OH-------OHCH2CH3

But in Propanoic acid CH3CH2COOH

This has more extensive H- bonding Because here H-bonding occur from two Oxygen atoms . One is C=O oxygen and other is -OH oxygen.

2.Propanoic acid is more acidic than ethanol because it has acidic Hydrogen . The anion formed after the removal of Hydrogen from Propanoic acid is stabilized by resonance but this does not occur in alcohol. look at the resonance of COO- of carboxylic acids;

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
