How do you identify primary secondary and tertiary alcohols?

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.

How can you distinguish between primary and secondary alcohols?

In a primary (1°) alcohol, the carbon atom that carries the -OH group is only attached to one alkyl group. Example: Methanol, CH3OH. In a secondary (2°) alcohol, the carbon atom with the -OH group attached is joined directly to two alkyl groups.

How do you know if something is primary secondary or tertiary?

Primary carbons, are carbons attached to one other carbon. (Hydrogens – although usually 3 in number in this case – are ignored in this terminology, as we shall see). Secondary carbons are attached to two other carbons. Tertiary carbons are attached to three other carbons.

How will you distinguish between primary secondary and tertiary alcohol by Lucas test?

The Lucas reagent is an equimolar mixture of ZnCl2 and HCl . You shake a few drops of your alcohol with the reagent in a test tube. A tertiary alcohol reacts almost immediately to form the alkyl halide, which is insoluble and forms an oily layer. A secondary alcohol reacts within 3 min to 5 min.

How will you distinguish between primary secondary and tertiary amines with nitrous acid?

Reaction of an amine with nitrous acid (HO – N =O) is the distinguishing test between primary, secondary and tertiary amines as they react differently with nitrous acid. Nitrous acid is unstable, hence prepared instantly by the action of cold, dilute, hydrochloric acid on sodium nitrite.
