A compound of the formula C_(4)H_(10)O reacts with sodium and undergoes oxidation to give a carbonyl compound which does not reduce Tollen's reagent, the original compound is

Answer»

Diethyl ether
n-Butyl alcohol
Isobutyl alcohol
sec-Butyl alcohol

Solution :Because the compound react with Na, it may be alcohol, phenol or a carboxylic acid. As the compound on oxidation gives a carbonyl compounds which does not reduce Tollen's reagent, the compound FORMED on oxidation is a reagent, the compound is a ketone. Because only SECONDARY `(2^(@))` alcohols on oxidation yield KETONES, thethe original compound is a secondary alcohol.
