Final answer:
Option c: H3C-CH2-OH is the correct Lewis dot structure for the compound CH3CH2OH, also known as ethanol. It reflects the proper connectivity and number of bonds for each atom in the molecule.
Step-by-step explanation:
The student is asked to select the correct Lewis dot structure for the compound CH3CH2OH, which is known as ethanol. The correct structure for ethanol is option c: H3C-CH2-OH. This structure aligns with the provided information, including the molecular structure exercises and the hints about the bonding of different carbon groups (CH3, CH2) in various molecules, including ethers and alcohols like ethanol.
To determine the correct Lewis structure, we need to look at the number of bonds that carbon forms (typically four bonds), and the single bonds around oxygen that suggest it is also connected to a hydrogen atom. The condensed formulas help us visualize the connectivity of the atoms in the molecule, and among the options given, only option c correctly represents those connections in CH3CH2OH.
