Lassaigne's extract is boiled with dil. `HNO_(3)` before testing for halogens because

Sodium extract is heated with con. HNO_(3) before testing for halogens because

The LaSSaigen's extract is boiled with conc. HNO_(3) while testing for halogens. By doing so it :

(a) how is a mixture of two organic compounds separated, which have different solubilities in the ame solvent? (b) How is an organic liquid purified which decomposes below its boiling point? (c) Why is sodium extract boiled with HNO_3 before testing for halogens? (d) What type of organic compounds cannot be estimated by Kjeldahl's method? (e). What does blood-red colouration during Lassaigne's test indicate? (f). What happens when AgNO_3 solumtion is added to bromo methane?

Reaction of phenol with dil. HNO_(3) gives

Reaction of phenol with dil. HNO_(3) gives

For testing halogens in an organic compound with AgNO_(3) solution, sodium extract (Lassaigne's test) is acidified with dilute HNO_(3) . What will happen if a student acidifies the extract with dilute H_(2)SO_(4) in place of dilute HNO_(3) ?

The function of boiling the sodium extract with concentrated nitric acid before testing halogens is

When dil. HNO_(3) is electrolysed

Copper reacts with dil. HNO_3 to form a nitrate and

Sodium carbonate extract is acidified with HNO_(3) only in the identification of halides. Comment.
