Differentiate between the principle of estimation of nitrogen in an organic compound by (i) Dumas method and (ii) Kjeldahl’s method.

Assertion (A) The Duma’s method is of more general application to nitrogen containing organic compounds than the Kjeldahl’s method. Reason (R ) The Kjeldahl’s method does not give satisfactory results for eompomds in which nitrogen is directly linked to oxygen.

In dumas method for the estimation of nitrogen in an organic compound,nitrogen is determined in the form of:

Kjeldahl method for estimation of nitrogen is not applicable to

Sulphur in an organic compound can be estimated by Dumas method. IF yes, explain method.

In the Duma's method of estimation of the organic compound is finaly converted into

Kjeldahl's-method for detection of nitrogen in organic compound, cannot be used in case of

Dumas method involves the determination of nitrogen content in the organic compound in the form of
