Answer
The structure for each compound is written below.
Work Step by Step
a) hex means 6 C in a straight chain. Draw 6 C in straight chain and numbering them from 1 to 6. Now, 3-hexene means there is a double bond present between C3 and C4 position. Place a double bond in that position and remaining valency of C atoms are filled with H atom to get the structure.
b) hept means 7 C in straight chain. Draw 7 C in straight chain and numbering them from 1 to 7. '2,4-heptadiene' means that two (di) double bonds (ene) are present at C2 and C4 position. Place two double bonds one between C2 and C3 & the other between C4 and C5 position. Remaining valency of C atoms is filled with H to get the structure.
c) oct means 8 C in straight chain. Draw 8 C in straight chain and numbering them from 1 to 8. Now, 2-methyl means one methyl group is present at C2 position. 3-octene means one double bond (ene) is present in between C3 and C4 position. Remaining valency of C atoms is filled with H to get the complete structure.
