The statement "Alkynes can be prepared by dehydration of alcohols" is False.

Explanation:

Dehydration reactions typically involve the loss of water from alcohols to form alkenes, not alkynes. When an alcohol undergoes dehydration, a molecule of water (H₂O) is removed, resulting in the formation of a double bond, which produces an alkene. To convert alcohols to alkynes, further dehydrogenation processes need to occur, which involve additional reactions beyond simple dehydration.

For example, an alcohol can first be dehydrated to form an alkene, and this alkene can then undergo another reaction, such as a halogenation followed by elimination or a direct dehydrogenation, to eventually form an alkyne. Therefore, the direct dehydration of alcohols yields alkenes, and not alkynes, making the statement false.
