Question

The final product of oxidation of 2-propanol with hot conc. $HN{O_3}$ is:
A.Propanol
B.Ethanoic acid
C.Propanone
D.Ethanol

Answer 1

Propanol generally belongs to the primary type of alcohol. Its formula is $C{H_3}C{H_2}C{H_2}OH$ .Further, it undergoes oxidation with $HN{O_3}$ and acetic acid is formed.

Complete step by step answer:
Isopropyl alcohol is basically a colorless, flammable chemical compound with a strong odor. It is a structural isomer of $1$propanol and ethyl methyl ether. Its general formula is ${C_3}{H_8}O$ . It was first discovered by Gustave C. B. Chancel in the year 1853 while conducting the fractional distillation of fuel oil.
Moreover, it is usually produced industrially by catalytic hydrogenation of propionaldehyde. Now, when 2-propanol is oxidized with hot conc. $HN{O_3}$ , the final product that is obtained is ethanoic acid or it is also known as acetic acid. The reaction is as shown:
$C{H_3}CHOHC{H_3}\xrightarrow{{[O]}}C{H_3}COC{H_3}\xrightarrow{{[O]}}C{H_3}COOH + C{O_2} + H{}_2O$
Now, acetic acid or ethanoic acid is the second simplest carboxylic acid and is essentially a methyl group with a carboxyl functional group attached to it. It is produced industrially via carbonylation of methanol. Moreover, it possesses strong corrosive powers in its concentrated form even though it is a weak acid. Some metals such as magnesium, zinc and iron undergo corrosion when exposed to acetic acid.
Hence, option B is correct.

Note: There are several potential uses of propanol such as it is used as a solvent, in medicines, cosmetics, fuel etc. Most commonly, it is used as a solvent or it is used to produce other solvents such as soaps, dye solutions, window cleaner and many more. Moreover, it is a much safer chemical than other synthetic alcohol solutions.
