Kjeldahl method for estimation of nitrogen is not applicable to
Kjeldahl method for estimation of nitrogen is not applicable to
Updated On: Jun 14, 2022
- pyridine
- hexamethylene diamine
- propan-1-amine
- 2-phenylethanamine
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Kjeldahl method can not be used for compounds having azo groups $(-N = N-)$ nitroso $(-NO)$ azoxy compounds
and nitrogen in the ring (pyridine, quinoline etc.) Since, nitrogen in these compounds is not quantitatively converted into ammonium sulphate.
and nitrogen in the ring (pyridine, quinoline etc.) Since, nitrogen in these compounds is not quantitatively converted into ammonium sulphate.

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024
