About the CH3CH2OH, ethanol

Question

CH3CH2OH, ethanol,

Does it molecular exhibit resonance? If so, how to show all possible forms?

And does it molecule have any isomers? If so, how to show Lewis structures of them as well?

Answer 1

Ethanol doesn't show resonance structures.

An isomer of ethanol would be dimethyl ether H3C - O - CH3

I can't easily draw Lewis dot, but this will have 20 valence electrons with O in the center and a single bond to each C atom. The C atoms will each have 3 H atoms and the central O will have 2 lone pairs of electrons.
