does any1 know how to draw it ?? im confused!

You never need to do a dot cross of benzene. So other than that it's just like another alcohol.

with benzene there is a carbon righ sigma bonded together with alternative pi bonds.. three electrons go round the whole ring rather than stay at one bond place which is why you draw the circle inside the hexagon

you could do it as

R-C(H2) -OH

where R represents C6H5 or the benzene ring
and this is called resonance, thats why there is only one isomer, not two (of benzene)

The pi bonds don't alternate!

The electrons are always moving in the ring, so in theory they do alternate.

In practice they don't.

In practice they don't and in theory, well - it rather depends which theory you use! Generally, the consensus is that there isn't really anything to alternate.

...three electrons go round the whole ring...

All six p electrons are delocalised in the pi system.

What The Hell Is This Crap??? I Didnt Ask For That Info!! I Know It!! I Said Imconfused About Drawing The Dot N Cross Diagram Of Phenol... Im Confused On Hw To Put The Electrons In The Arene Ring
