Write the chemical formula and name of the compound which is the active ingredient of
all alcoholic drinks. List its two uses. Write chemical equation and name of the product
formed when this compound reacts with-
(i) sodium metal
(ii) hot concentrated sulphuric acid

Explanation

Chemical formula: `C_(2)H_(5)OH`
Name of compound: Ethanol, It is the active ingredient of all alcoholic drinks.
Uses of ethanol:
`*`It is used in medicines such as tincture iodine, cough syrups and many tonics.
`*` Ethanol is a very good solvent and is also soluble in water in all proportions. So it is
used in many chemical industries.
(i) `underset("Sodium")(2Na) + underset("Ethanol")(2CH_(3)CH_(2)OH) rarr underset("Sodium ethoxide")(2CH_(3)CH_(2)O^(-)Na^(+)) + underset("Hydrogen")(H_(2))`
The products formed are sodium ethoxide and hydrogen.
(ii) ` underset("Ethanol")(CH_(3)CH_(2)OH) underset (H_(2)SO_(4))overset(Hot.conc.) (rarr) underset ("Ethene")(CH_(2)=CH_(2))+ underset("Water")(H_(2)O)`
The products formed are Ethene and Water.
