When two sequential reactions are carried out without
drawing any inter!ediate co!"ound, the ste"s are
nu!#ered a#o$e or #elow the reaction arrow. %his
con$ention signifies that the first ste" occurs #efore the
second ste", and the reagents are added in sequence.O!itting the nu!#ers !eans they are "resent together.
