(a)
Interpretation:
To draw the structural formula for the compound.
Concept Introduction:
Structural formula is the spatial arrangement of atoms of a molecule in space.
In the condensed formula is a line-angle formula, the symbol for carbon and hydrogen atoms are not shown. Only carbon-carbon bonds are shown using lines. Single bonds are shown as 
double bond as 
and triple bond as 
. The carbon atoms are represented as vertices and end of lines.
Answer to Problem 12.23P
Explanation of Solution
3-Chloropropene.
Carbon atoms in the longest chain are 3.
-ene means a double bond is present at Carbon 1.
