Pentiin

Pentiin refers to any chemical compound that is an isomer of pentane. Pentane is an alkane with the chemical formula C5H12. As an isomer, pentiines share the same molecular formula but differ in their structural arrangement of atoms. The term "pentiine" specifically relates to molecules with a triple bond between two carbon atoms. Therefore, pentiine is not a direct chemical term but rather a descriptor for unsaturated hydrocarbons based on a five-carbon chain containing a triple bond. Such compounds would be classified as alkynes. For a five-carbon chain, potential alkyne structures include pent-1-yne and pent-2-yne, with the number indicating the position of the triple bond. These molecules are characterized by their reactivity due to the presence of the triple bond, which can undergo addition reactions. They are distinct from pentanes, which are saturated hydrocarbons with only single bonds.
