Question

Draw the condensed structure for each of the following:

a. (Z)-1,3,5-tribromo-2-pentene

b. (Z)-3-methyl-2-heptene

c. (E)-1,2-dibromo-3-isopropyl-2-hexene

d. vinyl bromide

e. 1,2-dimethylcyclopentene

f. diallyl amine

Short answer

All the structures are drawn using the IUPAC and E, Z nomenclature and they are given below.

Step-by-step solution

Drawing of structures from IUPAC name

We can draw the structures from the IUPAC name of the compound by using the following rules and these are as follows.

1. Find out the longest chain and do the numbering.

Ex, If a compound is 3-methyl-butan-1-ol, that means the longest chain name is butane.

2. Find out the positions of substituting groups in the longest chain.

Ex- for the above compound, Methyl is attached to the 3^rd position and the hydroxyl group is in 1 position of the skeletal chain or the main chain, So, I should be written in the 3^rd position and hydroxyl group in the 1^st position.

3. “n” in a compound designated non-branched compound.

4. N, N means the substitution of groups to N of amine groups.

E, Z nomenclature

When a double bond has same priority number in the same side, the structure is called Z nomenclature.

When a double bond has same priority number in the Opposite side, the structure is called E nomenclature.

Estimation of the structures

All the condensed structures of the compounds are given below.
