What functional groups are found in camptothecin?

Camptothecin contains a lactone functional group and a tertiary amine functional group in its structure.


Is benzyl alcohol considered a tertiary alcohol?

Benzyl alcohol is not considered a tertiary alcohol; it is classified as a primary alcohol. In benzyl alcohol, the hydroxyl group (-OH) is attached to a benzyl group, which is a phenyl group (C6H5) connected to a -CH2- group. Since the carbon atom bearing the hydroxyl group is attached to only one other carbon atom, it meets the criteria for a primary alcohol.


Why is tertiary alcohol more easily oxidized in acid medium than in neutral or alkaline medium?

In acidic medium, the hydroxyl group of the tertiary alcohol can be protonated, making it easier to lose a proton and form a carbocation intermediate, which is more stable due to hyperconjugation. This facilitates the oxidation process compared to in neutral or alkaline medium where the hydroxyl group is not protonated and the carbocation intermediate is less stable.


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.


What is -OH group?

The -OH group is called the hydroxyl group


How many isomers are there with molecular formula C7H14O and a five-membered ring and a tertiary alcohol group?

For the molecular formula C7H14O with a five-membered ring and a tertiary alcohol group, there are a limited number of isomers. A tertiary alcohol requires the hydroxyl (-OH) group to be attached to a carbon that is itself bonded to three other carbons. Given the constraints of forming a five-membered ring and maintaining a tertiary alcohol, there are 3 distinct isomers that fit these criteria.


What classification of alcohol is resistant to oxidation?

Primary alcohols are more resistant to oxidation compared to secondary and tertiary alcohols. This is because primary alcohols have a hydrogen atom attached to the carbon with the hydroxyl group, which can be oxidized to form an aldehyde or carboxylic acid.


Do alcohols contain a hydroxyl group?

Yes, alcohols contain a hydroxyl group (-OH) as their functional group. This hydroxyl group is bonded to a carbon atom in the alcohol molecule.


What group is an -OH group?

hydroxyl


Why can't tertiary alcohols be oxidized?

Simple answer ... you need at least one hydrogen attached to carbinol carbon. in other words, you have a hydrogen on the oxygen to give you the hydroxyl group that is attached to the carbinol carbon, but you also need a hydrogen coming off that carbon. The reason - your reagent, such as chromic acid, joins with the alcohol at the position of the hydroxyl group, which leads to an H2O molecule being shot off. The chromic acid provides the -OH of that water, but takes the H off the hydroxyl group to get the 2nd hydrogen atom. You would now have a chromate ester + water. The water then takes off a hydrogen atom attached to the carbinol carbon, which leaves the electrons to form a double bond with the Oxygen atom. Without the hydrogen attached to the carbinol carbon ... like in a tertiary alcohol ... oxidation could only take place by breaking carbon-carbon bonds, which requires severe conditions. Even if this did happen, you would get a mixture of products.

ID functional groups for PCP?

PCP consists of a phenyl group, a cyclohexane group, and a piperdine [(CH2)5NH] group. You can consider the piperdine group to be a tertiary amine.
