Question

Acetic acid is a _ _ _ _ _ volatile acid then ${H_2}C{O_3}$ .
A.Less
B.More
C.Equally
D.Can’t say

Answer 1

Acetic acid is also known as ethanoic acid. A dilute solution of acetic acid is produced by fermentation. Acetic acid is an important metabolic intermediate. It is present naturally in body fluids and in plant juices.

Complete step by step answer:
Acetic acid is manufactured by a process developed by the chemical company (Monsanto’s) in the $1960's$ . It involves rhodium-iodine catalyzed carbonylation of methyl alcohol $(C{H_3}OH)$ .
$C{H_3}OH + CO\xrightarrow{{Rh/{I_2}}}C{H_3}COOH$
Pure acetic acid is glacial acetic acid. It is a corrosive, colorless liquid.
Volatility is the measure of how easily a substance can vaporize. ${H_2}C{O_3}$ is carbonic acid.
Such acids are diluted with water. Acids when dissolved in water they form ions.
The bicarbonate ions in carbonic acid can form extensive intermolecular hydrogen bonds among themselves. These hydrogen bonds are strong and difficult to break thus increasing the boiling point. Such kind of hydrogen bonding is not present in acetic acid and therefore has lower boiling point than ${H_2}C{O_3}$ .
So, Acetic acid is more volatile than ${H_2}C{O_3}$ since it will boil faster as compared to ${H_2}C{O_3}$.
So the correct option is B.

Additional information:
Acetic acid is secreted and produced by bacteria like Acetobacter and Clostridium species. These bacteria are found in water, soil and food.

Note: Acetic acid is an important chemical reagent and has wide applications in industries. Carbonic acid is widely used in the production of soft drinks, artificially carbonated drinks. Carbonic acid is a dibasic acid while acetic acid is a monobasic acid. Both are weak acids.
