  2. If you draw out the chain you wil see that in (ii) Cl can be cis or trans to the main chain.

    You need to draw each of these, it is hard just from the names.

    why can't you convert cis-2-butene into trans-2-butene simply by undergoing a rotation/ The cis and trans isomers of 2-butene involve a pi bond as well as a sigma bond. To "rotate" the molecule, the pi bond must be broken
