    Hi
    I have to assign R or S to a) the back c on this link. It says it is S as it is anticlockwise however to me it looks as if it goes clockwise. Could anyone try and explain why it is anticlockwise.

    Thanks

    You need a password to access the paper. You'll have to draw it out for us.

    Yup password protected.

    The R and S assignation place the lowest priority (CIP rules) away from you and then look at the other groups. Don't forget that double bonds count twice in the priorities.

    The file is password protected. Perhaps you could take a screenshot and put it up here ?
