Q. For which of the following compounds Kjeldahl method can be used to determine the percentage of Nitrogen ?

JEE MainJEE Main 2013

Solution:

Kjeldahl’s method is not applicable for compounds containing nitrogen in nitro and azo groups and nitrogen present in the ring. Because nitrogen of these compounds does not change to ammonium sulphate under these conditions.
Hence only Alanine can be used to determine percentage of nitrogen.
