Benzene is a colourless, mobile and volatile liquid. Its boiling point is 80°C and freezing point is 5.5°C. It has
characteristic odour.
It is highly inflammable.
It is lighter than water.
It is immiscible with water but miscible with organic solvents…

Uses and general importance

Benzene is used mainly as an intermediate to make other chemicals. About 80% of benzene is consumed in the
production of three chemicals, ethylbenzene, cumene, and cyclohexane. Its most widely produced derivative is
ethylbenzene, forerunner to styrene, which is used to make polymers and plastics. Cumene…

Phenols take part in some typical acid reactions, reacting with sodium and bases to form ionic salts called phenoxides
releasing hydrogen gasses. Due to being a weak acid , phenols can also neutralise some alkali solutions forming a
phenol oxide and water.

Electrophilic substitution

Similarly to benzene phenols undergo electrophilic…
