Question

Statement I: Acetic acid production involves both aerobic and anaerobic processes
Statement II: Production of alcohol from glucose is an aerobic process and production of acetic acid from alcohol is an anaerobic process

Choose the correct option:

• A. Both statements are true
• B. Both statements are false
• C. Statement II is true but statement I is false
• D. Statement I is true but statement II is false

Answer 1

The correct option is D Statement I is true but statement II is false

Acetic acid is prepared from the fermented alcohol with the help of bacteria like Acetobacter aceti. Although the alcoholic fermentation of sugar is an anaerobic process, the conversion of alcohol to acetic acid is an aerobic process.

Anaerobic fermentation of ethyl alcohol $\left(C_2{H}_5\mathrm{OH}\right)$

$C_6{H}_{12}{O}_6\to 2C_2{H}_5\mathrm{OH}+2{\mathrm{CO}}_2$

Aerobic formation of acetic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$
