I am not familiar with $\singlebond$ etc.
In ConTeXt, one can also use a different mechanism (chem-str.mkiv):
\chemical{1,SINGLE,2,DOUBLE,3,TRIPLE,4}
Looking at the result of the above, I find that the spacing of DOUBLE
should be modified (to .25ex rather than .5ex), a question of
aesthetics?
Compare this with a third mechanism (mp-chem.mpiv, drawing a chemical
structure rather than writing an inline chemical formula):
\startchemical
\chemical[ONE,Z0,SB1,Z1,MOV1,Z1,DB1,MOV1,Z1,TB1,MOV1,Z1] [1,2,3,4]
\stopchemical
Ignore that the horizontal spacing is different, too, for the structure
ONE.
