How do you draw the following structural formulas: 2,4-dimethylhexane; 4-methyl-2-pentene; 4-chloro-7-methyl-2-nonyne

The answer to your question is given below

Explanation:

1. 2,4-dimethylhexane can be drawn as follow:

a. The parent name: Hexane i.e it contains 6 carbon atom.

b. The substitute group attached: Methyl i.e CH3 and it is at carbon 2 and 4.

c. Draw 6 carbon atom in a straight line and put CH3 at carbon 2 and 4. As shown in attach photo.

2. 4-methyl-2-pentene can be drawn as follow:

a. The parent name: pentene i.e it contains 5 carbon atom and the double bond is at carbon 2.

b. The substitute group attached: Methyl i.e CH3 and it is at carbon 4.

c. Draw 5 carbon atom in a straight line and put a double bond at carbon 2 and CH3 at carbon 4 as shown in attach photo.

3. 4-chloro-7-methyl-2-nonyne can be drawn as follow:

a. The parent name: nonyne i.e it contains 9 carbon atom and the triple bond is at carbon 2.

b. The substitute group attached:

i. Chlorine (Chloro) i.e Cl and it is at carbon 4.

ii. Methyl i.e CH3 and it is at carbon 7.

c. Draw 9 carbon atom in a straight line and put a triple bond at carbon 2, Cl at carbon 4 and CH3 at carbon and 7 as shown in attach photo.
