Given below is a four carbon skeleton of a hydrocarbon compound.
(a) Fill in the hydrogen atoms/bonds to form:
(i) a saturated hydrocarbon
(ii) an unsaturated hydrocarbon
(b) If the four-carbon skeleton is of a straight chained alkene, draw the structures of all the possible compounds.
If the four-carbon skeleton is of a straight chained alkyne:
(i) How many carbon atoms may NOT be bonded to any hydrogen atoms?
(ii) How many hydrogen atoms will there be in the compound?
