Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly Benzene, or benzol, is an organic Chemical compound and a known Carcinogen with the molecular formula C 6 H 6 Furan, also known as furane and furfuran, is a heterocyclic Organic compound. It is the parent of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Psoralen (also called psoralene) is the parent compound in a family of natural products known as Furocoumarins '

It is prepared by O-alkylation of salicylaldehyde with chloroacetic acid followed by dehydration of the resulting ether. Salicylaldehyde, or 2-hydroxybenzaldehyde is the Chemical compound with the formula C6H4CHO-2-OH In Chemistry, a dehydration reaction is usually defined as a chemical reaction that involves the loss of water from the reacting molecule Ether is a class of Organic compounds which contain an ether group — an Oxygen Atom connected to two (substituted Alkyl ^[1]
