Kjeldahl's method, where `N` of the organic compound i9s estimated as `NH_(3)`, works well for
(i) amines
(ii) amino acids
(iii) proteins
(iv) alkyl nitrites

A

(i), (iv)

B

(i), (ii), (iii)

C

(i), (ii), (iii), (iv)

D

(ii), (iii)

Text Solution

Verified by Experts

The correct Answer is:
B
Kjeldahl's method is inaccurate when applied to compounds containing `N` atoms linked to `N` of oxygen (e.g., nitrites, `RONO`, diazonium salts, `ArN_(2)Z`), but it works well for amines, proteins, and similar substances.
