The ammonia evolved by the treatment of 0.30 g of an organic compound for the estimation of nitrogen was passed in 100 ml of 0.1 M sulphuric acid. The excess of acid required 20 mL of 0.5 M solution hydroxide solution for complete neutralization. The organic compound is

The ammonia evolved by the treatment of 0.30 g of an organic compound

1.	The ammonia evolved by the treatment of 0.30 g of an organic compound for the estimation of nitrogen was passed in 100 ml of 0.1 M sulphuric acid. The excess of acid required 20 mL of 0.5 M solution hydroxide solution for complete neutralization. The organic compound is
Answer» acetamide benzamide urea thourea Solution :Excess of acid `=20xx0.5xx1` m.e.q. Acid taken initially `= 100xx0.1xx2` m.e.q. Acid used for neutralisation `(100xx0.1xx2)-(20xx0.5xx1)` `20-10=10` m.eq. `rArr NH_(3)` liberated = 10 m.eq. `% N = (NH_(3)" liberated (m.eq)")/("wt.of ORG. compound")xx1.4` `=(10xx1.4)/(0.3)=46.66% rArr` Urea has 46.66% N.
