Explanation:
Alcohol Reacting with Copper:
When vapours of an alcohol are passed over red hot copper, the alcohol undergoes dehydrogenation to give an olefin.
Tertiary Alcohol:
In this case, the alcohol must be tertiary in nature. Tertiary alcohols are the most reactive towards dehydrogenation reactions as they have a more stable carbocation intermediate formation during the process.
Formation of Olefin:
The dehydrogenation reaction leads to the removal of hydrogen atoms from the alcohol molecule, resulting in the formation of a double bond in the olefin product.
Red Hot Copper Catalyst:
The presence of red hot copper acts as a catalyst in this reaction, providing the necessary conditions for the dehydrogenation process to occur efficiently.
Therefore, based on the given information, the alcohol in this scenario is most likely a tertiary alcohol since it forms an olefin when reacted with red hot copper.
