Hi, Im stuck on question 1biii, on the chemistry A OCR specimen paper, theres a compound and you have to label the parts which is responsible for the EZ isomer but not sure why the other two are optical isomers.

Are optical isomers any organic molecule with a chiral carbon compound attached to 4 different atoms.
-----------------------------------------------------------------CH2
Does this mean for exam would-----------------OHC - C - H
------------------------------------------------------------------Ch2COOCH3


be classed as a
optical isomer or is it only if its attached to 4 different atoms and not groups.

It is not that they must be directly attached to four different atoms, it is that the atoms or groups of atoms must all be different.

Your example would be optically active, even though the chiral carbon is directly attached to three carbon atoms.

Thank you thats has cleared up my confusion, I always thought it was the atom it was attached to :P Iv gone over the question and now understand why they got that answer )
