In Lassaigne's extract of an organic compound, both nitrogen and sulphur are present, which gives blood red colour with Fe³⁺ due to the formation of

Organic chemistry is applied in pharmaceuticals, the food industry, the manufacture of polymers, agriculture, and environmental science. Most of the things that we use in daily life, such as soaps and medicines, are made of organic molecules.

The main difference between organic compounds and inorganic compounds is that organic compounds contain carbon atoms from bonds with hydrogen and other elements, whereas inorganic compounds don't have carbon atoms (except carbonates and cyanides).

In class 11 organic chemistry, the important chapters are hydrocarbons, classification of organic compounds, isomerism, method of purification of organic compounds, and Qualitative and quantitative analysis of organic compounds.

S 1 reaction depends on carbocation stability and cation form in 3 will be most stable.
