Concept explainers
(a)
Interpretation:
The skeletal structures for the given compounds has to be drawn including cis-trans isomers.
Concept introduction:
In skeletal structure or bond-line structure the carbon atoms and the hydrogen atoms which are attached to that carbon atom are not to show, rather the bonds in between carbon atoms and to the heteroatoms are drawn as line segments. For acyclic carbon chains it draws as in a zig-zag fashion and for cyclic chains of carbon it draws as a cyclic polygon. For representing a heteroatom attached to the carbon, use a line segment and label the heteroatom at the end of their line segment.
Cis-trans terminology is used for two non-similar groups attached
If the two identical groups are attached on each side of double bond in same side, then it is cis alkenes.
If the two identical groups are attached on each side of double bond in opposite manner, then it is Trans alkenes.
