Assertion : Acetic acid production involves both aerobic and anaerobic processes.
Reason : Production of alcohol from glucose is an aerobic process and production of acetic acid from alcohol is an anerobic process

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

C

Explanation

Acetic acid is prepared from fermented alcohols with the help of acetic acid bacteria, Acetobacter aceti. Alcoholic fermentation fo sugars is an anaerobic process but the conversion of alcohol to acetic acid is an aerobic process. This reactions occuring can be summarised as: Anaerobic formation of alcohol :
`C_(6)H_(12) O_(6) overset("Zymase complex")rarr underset("Ethyl alcohol")(2C_(2)H_(5)OH)+2CO_(2)`
Aerobic formation of acetic acid
`C_(2)H_(5)OH +O_(2) rarr underset("Acetic acid")(CH_(3)COOH)+ H_(2)O`
Acetic acid is either used as vinegar after ripening or in pharmaceuticals, colouring agents, insecticides, plastics, etc.
