Which compound has the lowest vapor pressure at 50°C?
2 answers:
Answer : The correct option is, (1) ethanoic acid.
Explanation :
The relation between the boiling point and the inter-molecular force of attraction is that the higher the boiling point, the stronger the inter-molecular force of attraction that means it requires more energy to breaks the forces between the molecules. Or, the higher the boiling point lower will be the vapor pressure.
In ethanoic acid, the hydrogen bonding will be stronger as compared to the propanone, ethanol and water.
In propanone, the dipole-dipole interaction occurs.
In ethanol and water, the hydrogen bonding occurs but polarity will be less.
Hence, ethanoic acid has the lowest vapor pressure at

0.1045M is the concentration of the original sulfuric acid solution
Explanation:
Titration is done to know the volume or concentration of unknown electrolyte.
Data given:
volume of acid = 50 ml
molarity of acid =?
volume of base NaOH = 34.62 ml
molarity of the base = 0.1510
For titration the formula used is,
Macid x Vacid = Mbase x V base
Putting the values in above equation:
M acid x 50 = 34.62 x 0.1510
Macid =
= 0.1045 M is the molarity of sulphuric acid solution used in neutralization of 0.1510 M base solution.
I have completed the reaction with both possible products. Below are the products formed both in presence and absence of peroxide. And have connected the proton with corresponding peaks with different color lines.
