Final answer:
The statement that CH3OH has at least one π bond is b) FALSE; methanol consists entirely of single bonds, which are sigma bonds.
Step-by-step explanation:
The statement that the molecule of CH3OH has at least one π bond is FALSE. Methanol (CH3OH) consists of one carbon atom bonded to three hydrogen atoms and one hydroxyl group (-OH). The carbon atom forms four sigma (σ) bonds: three with hydrogen atoms and one with the oxygen atom of the hydroxyl group. The bond between oxygen and hydrogen is also a sigma bond. There are no π bonds in methanol because all the bonds are single bonds, and π bonds are typically associated with double or triple bonds, as in the ethene molecule (C2H4) where the carbon atoms are connected by both a sigma and a π bond.
