(a) Draw two different possible structures of a saturated hydrocarbon having four carbon atoms in its molecule. What are these two structures of the hydrocarbon having same molecular formula called ? Write the molecular formula and the common name of this compound. Also write the molecular formula of its alkyne. [3]
Solution
a)
[structural formula: straight-chain H-C-C-C-C-H skeleton with H atoms, i.e. n-butane]
[structural formula: branched-chain isomer with a CH3 side branch, i.e. isobutane]
Isomers
C4H10
Butane
C4H6
