    I was able to identify the carbon with the red square above it as a chiral centre.

    My question is why the one with the green square NOT a chiral centre ?

    Its only bonded to 3 other atoms, and chiral centres need to be bonded to 4 different groups

    How ? There are four. One to the oxygen, one to the carbon below it, one to the carbon above it and the last to a hydrogen.

    When a carbon is a member of a benzene ring, it cannot be chiral, as it cannot bond to four different groups

    Exactly, four different groups are needed - 2 are carbons so it is not a chiral carbon

    No I don't think its bonded to a hydrogen, the oxygen has substituted the hydrogen in the synthesis of the molecule so no hydrogen is bonded to that carbon

    this guys right. as the carbon is in a benzene ring, it is only bonded to 3 things.

    The carbon above it and carbon below are identical and not different hence can't form optical isomers so yeah...not chiral

    Oh, I did a bit of research into the structure of the Benzene ring. It has alternating double bonds so...

    I got it now. Thank you everyone !
