Identify the incorrect statement
- A In organic compounds resonance effect operates only in unsaturated compounds and results in delocalisation of electrons.
- B Larger the number of methyl groups linked to the doubly bonded Carbon atoms, greater is the stability of the alkene.
- C The Prussian blue precipitate formed during Lassaigne's test for detection of Nitrogen in an organic compound is due to formation of \(\mathrm{Fe} e_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]_2 \times \mathrm{H}_2 \mathrm{O}\)
- D In the Carius method for estimation of halogens in an organic compound, the compound is heated with fuming nitric acid in presence of \(\mathrm{AgNO}_3\).
