What is a primary and secondary alcohol?
A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. … In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group. Examples of primary alcohols include ethanol and 1-butanol.
How do you identify a secondary alcohol?
A secondary alcohol is identified by the color change with the acidified potassium dichromate(VI) solution and the absence of a color change with the Schiff’s reagent might.
What is the difference between a secondary and tertiary alcohol?
In a secondary (2°) alcohol, the carbon atom with the -OH group attached is joined directly to two alkyl groups. In a tertiary (3°) alcohol, the carbon atom holding the -OH group is attached directly to three alkyl groups.
Is CH3OH a secondary alcohol?
Methanol, CH3OH, is counted as a primary alcohol even though there are no alkyl groups attached to the carbon with the -OH group on it.
Is phenol a secondary alcohol?
If this carbon is bonded to two other carbons, it is a secondary (2o) alcohol. If it is bonded to three other carbons, it is a tertiary (3o) alcohol. When the hydroxyl group is bonded directly to a benzene ring, the compound is classified as a phenol.
