The statement "Alkynes can be prepared from geminal dichlorides" is True.

Explanation:

Geminal dichlorides are compounds that contain two chlorine atoms attached to the same carbon atom. In organic synthesis, they can be converted into alkynes through dehydrohalogenation reactions. This process typically involves the elimination of two molecules of hydrogen halide from the geminal dichloride.

For example, when a geminal dichloride, such as 1,1-dichloroethane, undergoes treatment with a strong base (like potassium hydroxide or sodium amide), the base abstracts protons from the neighboring carbon atoms, leading to the formation of a triple bond between the carbons, resulting in the formation of an alkyne, such as ethyne.

Thus, the conversion of geminal dichlorides into alkynes through dehydrohalogenation is a well-established reaction in organic chemistry.
