उत्तर
The name of the compound which is the active ingredient of all alcoholic drinks is Ethanol, and its chemical formula is CH3CH2OH.
Uses:-
- Ethanol is used in medical wipes/swabs and antibacterial hand sanitizers.
- Ethanol is also used in body lotions as preservatives and stabilizers of its ingredients.
Chemical reactions of ethanol:-
(i) \[\ce{\underset{\text{Ethanol}}{CH3CH2OH}+\underset{\text{Sodium}}{Na}->\underset{\text{Sodium ethoxide}}{CH3CH2Na}+ \underset{\text{Hydrogen gas}}{H2}}\]
(ii) \[\ce{\underset{\text{Ethanol}}{CH3CH2OH2}+\underset{\text{Sulphuric acid}}{H2SO4(conc.)}->\underset{\text{ethene}}{C2H4}+\underset{\text{water}}{H2O}}\]
