When drawing a skeletal formula, what is the difference between an angular version and a linear version?
I was asked to draw the Z isomer of Resveratrol:
For which I drew:
However the markscheme states that:
skeletal structure must be correct and angular not linear
I haven't come across the difference between the two before and can't find anything on google to suggest one. Their drawing of the correct answer is equivalent to mine, however I am concerned that I may have drawn the linear version as my benzene rings are in a line and theirs are not. What am I missing here?
