Dehydrogenation of alcohol

​When the vapours of a primary alcohol are passed over copper heated at 573K, the corresponding aldehyde is formed. When the vapours of a secondary alcohol are passed over copper heated at 573K, the corresponding ketone is formed.

What happens when tertiary butyl alcohol?

As you can see the tertiary butyl alcohol has been dehydrated into an alkene. So the answer to the above question is option (C) 1-butene is formed. Additional information: The formation of the double bond takes place in such a way as to ensure maximum number of hyperconjugative structures.

What happens when primary secondary and tertiary alcohols are passed over red hot copper?

When the vapours of a primary or a secondary alcohol are passed over heated copper at 573K, dehydrogenation takes place and an aldehyde or a ketone is formed. In the case of tertiary alcohols, it goes dehydration.

When Vapours of alcohol are passed over hot reduced copper alcohol is converted into alkene the alcohol is 1 point?

Which alcohol can be oxidized to a ketone?

The oxidation of alcohols is an important reaction in organic chemistry. Primary alcohols can be oxidized to form aldehydes and carboxylic acids; secondary alcohols can be oxidized to give ketones. Tertiary alcohols, in contrast, cannot be oxidized without breaking the molecule’s C–C bonds.

What does Cu at 573 K do?

Answer. When the vapour of a primary or a secondary alcohol are passed over heated copper at 573 k , dehydrogenated takes place and an aldehyde or a keton is firmed . In case of tertiary alcohol , it goes dehydration .

What happens when tertiary butyl alcohol is treated with copper at 573K?

Alcohols are oxidised by passing their vapours over heated copper. 1° alcohols are oxidised to aldehydes, 2° to ketones while 3° alcohols undergo dehydration to form alkenes. Was this answer helpful?
