Question

An organic compound is estimated through Dumas method and was found to evolved 6 moles of CO 2, 4 moles of H 2 O and 1 mole of nitrogen gas. The formula of the compound is (A) C 6 H 8 N (B) C 12 H 8 N (C) C 12 H 8 N 2 (D) C 6 H 8 N 2

Tardigrade Admin · Accepted Answer

In Dumas method, organic compound is heated with dry cupric oxide in a combustion tube in the atmosphere of

C O_{2}

. Upon heating,

C

and

H

present are oxidised to

C O_{2}

and water vapours while

N_{2}

is set free.
Let, the molecular formula of the organic compound (

1 m o l)

be

C_{x} H_{v} N_{z}

. In Dumas method,

∴

Molecular formula of the compound is

C_{6} H_{8} N_{2}

.
