Which among the following alcohols will be the most reactive for dehydration?

Which alcohol is more reactive for dehydration?

Since the carbocation is most stable in the case of tertiary alcohols, the rate of dehydration is highest for tertiary alcohols in comparison to secondary and primary alcohols.

Which of the following alcohols will give the most stable carbocation during dehydration *?

The tertiary carbocation formed during dehydration of 2-methyl-2-propanol is most stable.

Do primary alcohols undergo dehydration?

Primary alcohols dehydrate through the E2 mechanism. … Secondary and tertiary alcohols dehydrate through the E1 mechanism. Similarly to the reaction above, secondary and tertiary –OH protonate to form alkyloxonium ions. However, in this case the ion leaves first and forms a carbocation as the reaction intermediate.

Which alcohol is most easily dehydrated Mcq?

3-methyl pentanol-3 will be dehydrated most readily since it produces tertiary carbonium ion as intermediate.

Which will dehydrate most easily?


Which alcohol is more stable?

Tertiary alcohols are more stable than primary alcohol, because the oxygen atom in the alcohol imposes negative I effect and pulls all the electrons towards it due to high electronegativity. This develops partial positive charge in central carbon atom.

Which of the following alcohol is most soluble in water?

Explanation: Because the lower alcohols are very soluble in water, propanol is the most soluble.

Which of the following alcohols would be most soluble in water?

Hence, glycerol has the highest solubility in water and so the correct option is D.

Why does alcohol cause dehydration?

Alcohol also reduces how much vasopressin your body makes. Vasopressin is an antidiuretic hormone. It causes the body to hold onto water, which typically limits how much urine your kidneys make. The action of suppressing this hormone exacerbates the diuretic effect and leads to dehydration.
