(a)
Interpretation: The four structures having same physical properties like boiling point, melting point, density etc needs to be determined.
Concept Introduction : Cis-trans isomerism is also known as Configurational or geometrical isomerism. The prefixes cis and trans are Latin words in which ‘‘cis’’ represents ‘‘this side of’’ and ‘‘trans’’ represents ‘‘the other side’’. This type of isomerism occurs in unsaturated compounds (i.e. double bonds) or cyclic compounds depending on the presence of substituted groups in a molecule.
(b)
Interpretation: The structure from the given four structures which are trans isomers needs to be determined.
