Is this how to draw optical isomers please look and confirm.

Is this right in terms of where the dashes and wedges go. Etc etc thanks.

Is that bit in the middle supposed to be a C? :lol:

I believe that would get you the marks. The triangles used and 3D arrangements tend to vary - I'd say use filled in black ones that come of the central carbon like this C< when the bond is protruding from the page ('at' you from a 3D perspective) and a lined one when it's pointing 'away' from you like this C>, exactly like you've done. Hope you see what I mean.

I don't think you have to have it precisely any way as long as it indicates 3D bonds and the correct atoms.

You have to make sure that the lines point directly to C and not to O or H.
Also if you write CH3 on one side, do not write H3C on the other.
This is what examiners write about these kind of questions in examiner's report.

thanks. Btw i know that the lines go directly to the C not the H but since it was in word i couldnt get accuracy. By the way what do you mean no CH3 on one side and H3C on the other how do u show that it is the mirror image then?
