Question

How many products are formed from the monochlorination of ethylcyclohexane including stereoisomers?

Answer 1

From the monochlorination of ethylcyclohexane including the stereoisomers, nine products can be formed

• Monochlorination of an alkane involves replacing a chlorine atom with one of the hydrogens in the alkane. .These conditions cause a division of the chlorine molecule into chlorine-free radicals.

• In seven products, chlorine is direct attached to cyclohexane ring. These products are -

1. 1-ethyl-1-chlorocyclohexane

2. cis-1-ethyl-2-chlorocyclohexane

3. trans-1-ethyl-2-chlorocyclohexane

4. cis-1-ethyl-3-chlorocyclohexane

5. trans-1-ethyl-3-chlorocyclohexane

6. cis-1-ethyl-4-chlorocyclohexane

7. trans-1-ethyl-4-chlorocyclohexane

• The other two with the chlorine are attached to the side chain. These products are -

8. 1-(1-chloroethyl)cyclohexane (C6H11-CHClCH3)

9. 1-(2-chloroethyl)cyclohexane (C6H11-CH2CH2Cl)
