2.Draw all the structures of all the constitutional isomers of C5H12. Label all those isomers that are straight-chain hydrocarbons.
3. Build the cis and trans isomers of CH3CH=CHCH2CH3, and draw their structures below. Label each structure as cis or trans.
4. Build cyclohexane (C6H12, a cyclic hydrocarbon), and rotate the bonds to obtain the boat and chair conformations.
5. Build cyclohexene [C6H10] and benzene [CH6], and draw their structures below.
