Hence, alcohol given in
option C
will have the fastest rate of dehydration. Thus, option C is the answer.
Which of the following will undergo dehydration with fastest rate?
Explanation: Dehydration reactions of alcohols leads to the formation of carbocations as is more stable than secondary and primary, thus,
tertiary alcohol
would undergo dehyderation fast.
What is the order of dehydration of alcohol?
The order of the ease of dehydration of alcohols is:
tertiary > secondary > primary
. Secondary and tertiary alcohols are best dehydrated by dilute sulfuric acid.
What is a tertiary alcohol structure?
A tertiary alcohol is a
compound in which a hydroxy group, ‒OH, is attached to a saturated carbon atom which has three other carbon atoms attached to it
.
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.
Which alcohol is more is dehydrated?
“The higher the alcohol content a drink has (or is absorbed in your body), the greater the diuretic and dehydration effect.” Drinks with a higher alcohol content — and therefore more potential to dry you out — include
vodka, gin, rum, and whisky
.
What is a common reagent for alcohol dehydration?
The acid catalysts normally used in alcohol dehydration are either
concentrated sulfuric acid or concentrated phosphoric(V) acid, H
3
PO
4
.
Which alcohol reacts faster with HBr?
2-methyl propane-2-ol
is tertiary alcohol and thus, reacts fastest with HBr.
Is CH3CH2CH2OH a tertiary alcohol?
Expert Answers
1-propanol is
considered a primary alcohol
, because the hydroxyl group (-OH) is attached to the first carbon atom in the chain. It has the chemical formula of CH3CH2CH2OH. 1-propanol is an organic compound, which means it has mostly as its formula atoms of carbon and hydrogen.
What is an example of tertiary alcohol?
For example (CH
3
)
3
COH
is a tertiary alcohol is commonly known as tert-butyl alcohol. This would be named 2-methylpropan-2-ol under IUPAC rules, indicating a propane chain with methyl and hydroxyl groups both attached to the middle (#2) carbon.
How do you know if alcohol is tertiary?
Alcohols are organic molecules containing a hydroxyl functional group connected to an alkyl or aryl group (ROH). If the hydroxyl carbon only has a single R group, it is known as primary alcohol. If it has two R groups, it is a secondary alcohol, and
if it has three R groups
, it is a tertiary alcohol.
Which alcohol is more stable?
so it will become more stable there for it is thermodynamycally favorite. so the reactivity is heigher than primary or secondary alcohol.
Tertiary alcohols
are more reactive because the increased number of alkyl groups increases +I effect. So, the charge density on carbon atom increases and hence around oxygen atom.
Which of the following carbocation is most stable?
Now if a greater number of alkyl groups is attached to the positively charged carbon, there will be greater dispersal of positive charge on the alkyl groups and hence, more will be the stability of the carbocation. Therefore,
${{3}^{o}}$ carbocation
is most stable followed by ${{2}^{o}}$ and ${{1}^{o}}$ carbocations.
Which among the following alcohols will be the most reactive for dehydration?
Since the carbocation is most stable in the case of
tertiary alcohols
, the rate of dehydration of alcohols is highest for tertiary alcohols in comparison to secondary and primary alcohols.
What alcohol makes you pee the most?
Beer, wine, liquor — alcohol in any form
makes you need to pee more. It also interferes with brain signals to the bladder about when to go. So limit how much you drink, or stop drinking if you have sensitivity.
Which alcohol causes less dehydration?
A single, one-and-a-half-ounce shot of liquor could contain up to a whopping 70 percent of alcohol content. That makes
beer
the clear contender as the least dehydrating, with a big caveat. As important as alcohol content may be, even more important is how much you drink in a given sitting.
