Question

how is benzene formed?

Answer 1

Benzene is a cyclic hydrocarbon with a chemical formula C6H6, that is, each carbon atom in benzene is arranged in a six-membered ring and is bonded to only one hydrogen atom. According to molecular orbital theory for benzene structure, benzene ring involves the formation of three delocalized π – orbitals spanning all six carbon atoms, while the valence bond theory describes two stable resonance structures for the ring.

Benzene is one of the most fundamental compounds used in the manufacturing of various plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs, and pesticides. Naturally, benzene is produced through volcanoes and forest fires. There are various laboratories and industrial techniques existing for the preparation of benzene. Commercially, benzene is chiefly obtained from coal tar.

Several types of bronze are used, commonly B20 bronze, which is roughly 20% tin, 80% copper, with traces of silver, or the tougher B8bronze which is made from 8% tin and 92% copper. As the tin content in a bell or cymbal rises, the timbre drops
