What is the difference between Dehydration of primary secondary and tertiary alcohol?

Answer 1

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

Answer 2

primary alcohol is more reactive than secondary alcohol when OH bond breaks while when CO bond breaks secondary alcohol is more reactive than primary alcohol because of the stability of carbocation due to more hyperconjunating structures(Pakistan)

Answer 3

This is true for dehydration of alcohols. The Tertiary alcohols have high stearic hindrance and after dehydration it is converted into an alkene so to reduce the stearic hindrance tertiary alcohols undergo fast dehydration process.

Answer 4

If the C atom bind to -OH only have 1 carbon chain it is a Primary Alcohol.Eg- CH3-CH2-OH If the C atom bind to -OH is binded to 2 carbon chains it is a secondry alcohol.Eg- OH l CH3-CH-CH3 If the C atom bind to -OH is binded to 3 carbon chains,it is a tritiary alcohol.Eg- OH l CH3-C-CH3 l CH3

Answer 5

All alcohols (except methanol) may undergo dehydration process in presence of dehydrating agent as sulphuric acid but their rates of reactions are different, tertiary alcohols dehydrate at normal temperature within seconds, secondary alcohols take 3 to 5 minutes and primary only on heating. (Lucas test).

Answer 6

A carbon atom directly attached to three other carbon atoms is a Tertiary carbon and alcohols in which 'OH' group is attached to tertiary carbon atom are tertiary alcohols as (CH3)3COH
