Rule 2: If two substituent atoms attached to the stereocenter have the same priority,the atom on the right of a hydrogen atom bonded to chiral carbon is a substituent of higher priority.
Rule 3: Double and triple bonds are treated as if they were single,and the atoms in them are duplicated or triplicated at each end by the particular atoms at the other end of the multiple bond.
