Anisole, also known as methoxy benzene,
is a colorless
liquid
with a smell
similar to that of anise
seed, and can be quite nauseating. Anisole is more electron
rich than benzene
because of the resonance effect of the methoxy
group upon the aromatic ring. This resonance effect has a greater effect upon
the pi cloud of the ring than
the inductive effect where the electronegative
oxygen
exerts a pull on the electron density in the benzene ring
through the sigma bond.
It is a clear colorless liquid.
