Outline a mechanism for the dehydration of 4-methylcyclohexanol catalyzed by phosphoric acid?

The reaction causes the protonation of the alcohol group, which causes it to turn into a water, which is a good leaving group. As a result, the water leaves, creating a carbocation with a positive charge. The carbocation then loses the proton (positive charge) forming a mixture of alkenes.

The mechanism of dehydration of 4-methylcyclohexanol?
You need to use a strong acid, such as H3PO4 or H2SO4.
What is he chemical mechanism by which cells make polymers from monomers?
Dehydradtion reactions cause cells to make polymers from monomers.
What is difference between process and mechanism?
process is process and mechanism is mechanism.
What is the mechanism for the aldol condesation reaction of acetone and p-anisaldehyde?
Write a reaction mechanism for cinnamaldehyde and acetone
What is reaction mechanism of uric acid and ascorbic acid?
give structure of reaction mechanism of uric acid
What is the mechanism that your body uses to create polymers from monomers?
Dehydration reaction.
What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.
3 If Acid-catalyzed dehydration of 22-methyl-1-hexanol gave a number of isomeric alkenes including 2-methyl-2-heptene Write a step-wise mechanism for the formation of 2-methyl-2-heptene?
problem here.... can't form heptene (7 carbon chain) from hexanol (6 carbon chain) without another C-C bond being formed, this can't result from dehydration

Is dehydration the chemical reaction to make a polymer?
Yes, monomers are connected by a reaction in which two molecules are covalently bonded to each other through loss of a water molecule; this is known as condensation reaction, specifically a dehydration reaction. There are other mechanisms and reactions to make polymers though. Dehydration is just one of them but not the only one. A poly-alcohol reacting with a poly-acid with removal of water (dehydration) will produce a polyester for example.
What is the type of reaction that occurs when complex molecules are formed from simpler molecules and water is removed?
The condensation polymerization takes place by removal of water molecules from organic molecules as formation of Bakelite , Terylene and Nylon. in plants starch is also formed by this mechanism from Glucose molecules.
What is the mechanism of dehydration?
Dehydration leads to three main responses. First receptors in mouth detect dryness and stimulates thirst mechanism making you want to drink water. secondly, low blood volume causes decrease blood flow to kidneys resulting in dercrease glomerular filtration rate. this causes body to respond by decreasing quantity of water in urine (ADH) thirdly, you will have low blood pressure and this will be detected by baroreceptors and they will bring up the pressure by means of vasoconstriction.
What is he chemical mechanism by which cells make polymers from monomers?
Dehydradtion reactions cause cells to make polymers from monomers.
Under what conditions would the guard cells close the stomates?
To prevent excess water loss through transpiration - normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.
Can drinking epsom salt while pregnant cause a miscarrage?
That can dehydrate the mother by causing vomiting and diarrhea. If she is near death from dehydration, the baby may die and miscarry. That would be about the only mechanism for magnesium sulfate to work as an abortifacient.
