What is the difference between Dehydration of primary secondary and tertiary alcohol?
In a primary (1°) alcohol, only attached to one alkyl group; In a secondary (2°) alcohol, attached two alkyl groups & tertiary (3°) alcohol, attached three alkyl groups
Actually, that person has you more confused. This is an easy way to remember what is 1 degree, 2 degree or 3 degree of Alcohols.
1 degree: R-- CH2 -- OH
2 degree: R2 -- CH -- OH
3 degree: R3 -- C -- OH
R = CH3

How do you convert secondary alcohol to tertiary alcohol?
A secondary alcohol can be converted to a tertiary alcohol by subjecting it to an acid-catalyzed rearrangement reaction known as a pinacol rearrangement. In this process, the secondary alcohol undergoes a rearrangement to form a more stable tertiary alcohol through a carbocation intermediate.
How acetone can be converted into tertiary butyl alcohol?
Acetone can be converted into tertiary butyl alcohol through a multistep process. First, acetone is converted to isopropanol using a reducing agent like sodium borohydride. Then, isopropanol is converted to diisopropyl ether using an acid catalyst like sulfuric acid. Finally, diisopropyl ether is converted to tertiary butyl alcohol through acid-catalyzed dehydration.
What does chromic acid test and lucas test indicate?
The chromic acid test is used to identify the presence of primary or secondary alcohols by observing a color change from orange to green or blue. The Lucas test is used to differentiate between primary, secondary, and tertiary alcohols by observing the formation of an alkyl chloride precipitate.
What happens to a tertiary alcohol with lucas reagent?
A tertiary alcohol does not react with Lucas reagent (ZnCl2 and HCl) and does not form a white precipitate, meaning it does not undergo a substitution reaction. Lucas reagent is primarily used to test for the presence of primary or secondary alcohols, as they react to form alkyl chlorides which are insoluble and precipitate out.
Can C3H6O be a secondary alcohol?
Methanol is a primary alcohol. You can't have a secondary alcohol until you get to propanol, where 1-propanol is a primary alcohol and 2-propanol is a secondary alcohol (also called sec-propyl alchohol or isopropanol). Secondary alcohols are alcohols where the -OH group is attached to a carbon that has two carbon groups attached to it. The first tertiary alcohol is t-butyl alcohol, otherwise known as 2-methyl-2-propanol. In that molecule the -OH group is attached to a carbon that has three carbon groups attached to it.
How do you convert secondary alcohol to tertiary alcohol?
A secondary alcohol can be converted to a tertiary alcohol by subjecting it to an acid-catalyzed rearrangement reaction known as a pinacol rearrangement. In this process, the secondary alcohol undergoes a rearrangement to form a more stable tertiary alcohol through a carbocation intermediate.
Is a 2-methylpentan-3-ol a primary or secondary or tertiary alcohol?
it is a secondary alcohol
What is the relative reactivity of Secondary and tertiary alcohols towards oxidation with potassium permanganate?
Tertiary alcohols are more reactive towards oxidation with potassium permanganate compared to secondary alcohols. This is because the presence of more alkyl groups in tertiary alcohols stabilizes the intermediate carbocation formed during oxidation.
Why do secondary and primary alcohol prove to be more reactive than tertiary alcohols?
Primary and secondary alcohols are more reactive than tertiary alcohols due to their structure, which allows for easier protonation and subsequent reaction with electrophiles. Primary and secondary alcohols have fewer steric hindrances compared to tertiary alcohols, making it easier for nucleophiles to approach and react with the hydroxyl group. Additionally, the carbon in tertiary alcohols is more stable and less likely to participate in reactions, such as dehydration or oxidation, compared to the more reactive primary and secondary alcohols.
Compare the relative ease of oxidation of primary secondary and tertiary butyl alcohol toward acid dichromate based on the time required for the solution to change color?
primary alcohols react the fastest, with secondary alcohols next and tertiary alcoholsnot reacting at all. This is because the mechanism of this reaction is Sn1 which is a substituion reaction that favors attack on less crowded molecules
Linalool a tertiary alcohol?
Linalool is not a tertiary alcohol; it is a secondary alcohol. Tertiary alcohols have three alkyl groups attached to the carbon bearing the hydroxyl group, whereas linalool has two alkyl groups attached to this position.
How acetone can be converted into tertiary butyl alcohol?
Acetone can be converted into tertiary butyl alcohol through a multistep process. First, acetone is converted to isopropanol using a reducing agent like sodium borohydride. Then, isopropanol is converted to diisopropyl ether using an acid catalyst like sulfuric acid. Finally, diisopropyl ether is converted to tertiary butyl alcohol through acid-catalyzed dehydration.
What classification of alcohol undergoes oxidation to yield a ketone?
A secondary alcohol undergoes oxidation to yield a ketone; a primary alcohol forms an aldehyde instead, and a tertiary alcohol usually does not form either a ketone or an alcohol, because the carbon having the OH group in a tertiary alcohol already has three bonds to other carbon atoms and therefore cannot form a double bond to oxygen without more extensive breaking of other bonds in the tertiary alcohol.
Alcohol in which the hydroxyl is attached to a carbon attached to three other carbons?
Tertiary
What does chromic acid test and lucas test indicate?
The chromic acid test is used to identify the presence of primary or secondary alcohols by observing a color change from orange to green or blue. The Lucas test is used to differentiate between primary, secondary, and tertiary alcohols by observing the formation of an alkyl chloride precipitate.
Why does bleach oxidize 2-methylcyclohexanol but not 1-methylcyclohexanol?
Because 2- methylcyclohexanol is a secondary alcohol (2 R- groups) and can be oxidized to a ketone quite easity whereas 1- methylcyclohexanol is a tertiary alcohol (3 R- groups) and is not easily oxidized. Tertiary alcohols in general are very difficult to oxidize.
What happens to a tertiary alcohol with lucas reagent?
A tertiary alcohol does not react with Lucas reagent (ZnCl2 and HCl) and does not form a white precipitate, meaning it does not undergo a substitution reaction.
