Write a reasonable and detailed mechanism for the dehydration of 4-methylcyclohexanol in the presence of sulfuric acid to form 4-methylcyclohexene. use curved arrows the show the flow of electrons and draw the structures of all intermediates and byproducts formed in the course of the reaction.

Reaction mechanism follows E1 (unimolecular elimination) pathway

Explanation:

In presence of sulfuric acid, 4-methylcyclohexane undergoes E1 elimination reaction to produce 4-methylcyclohexene.

In the first step, -OH group gets protonated by sulfuric acid.

In the second step, dehydration takes place to produce a carbocation.

In the third step, deprotonation takes place to produce a double bond.

Full reaction mechanism has been shown below.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
