For alkenes or alkynes, the unsaturation must get the smallest possible number to name them. True False

## Step 1<br />The problem statement is about the nomenclature of alkenes and alkynes in organic chemistry. The statement suggests that the unsaturation must get the smallest possible number to name them.<br /><br />## Step 2<br />In the IUPAC (International Union of Pure and Applied Chemistry) nomenclature system, the position of the unsaturation (double or triple bond) is indicated by the lowest possible number. This is done to provide a consistent and unambiguous way to identify the compound.<br /><br />## Step 3<br />For example, in the compound 1-butene, the double bond is between the first and second carbon atoms, hence the name 1-butene. If the double bond were between the second and third carbon atoms, the compound would be named 2-butene.<br /><br />## Step 4<br />Similarly, for alkynes, the position of the triple bond is also indicated by the lowest possible number. For example, in 1-butyne, the triple bond is between the first and second carbon atoms.<br /><br />## Step 5<br />Therefore, the statement is true. The unsaturation must get the smallest possible number to name alkenes and alkynes.
