Question

Kjeldahl's method cannot be used to estimate nitrogen for which of the following compounds ? (A) C6H5NO2 (B)  (C) CH3CH2-C≡ N (D) C6H5NH2

Tardigrade Admin · Accepted Answer

Kjeldahl's method for estimation of nitrogen is not applicable for nitrobenzene C6H5NO2. because reaction with H2SO4, nitrobenzene can not give ammonia.

Q. Kjeldahl's method cannot be used to estimate nitrogen for which of the following compounds ?

$C_{6} H_{5} N O_{2}$

$C H_{3} C H_{2} - C \equiv N$

$C_{6} H_{5} N H_{2}$

Kjeldahl's method for estimation of nitrogen is not applicable for nitrobenzene $C_{6} H_{5} N O_{2}$ . because reaction with $H_{2} S O_{4}$ , nitrobenzene can not give ammonia.
