Which of the following statements correctly describes the Lewis dot structure of the neutral compound C2H5F?

• A. The fluorine atom is bonded to a carbon atom and has three lone pairs of electrons.
• B. Each carbon atom in the molecule has one lone pair of electrons.
• C. The molecule contains a double bond between the two carbon atoms.
• D. The fluorine atom is bonded to a hydrogen atom and has two lone pairs of electrons.

Answer: (A)

Verified step by step guidance

1. Identify the molecular formula and structure of C2H5F, which is an ethyl fluoride molecule consisting of two carbon atoms, five hydrogen atoms, and one fluorine atom.
2. Recall that in Lewis structures, carbon typically forms four bonds with no lone pairs, hydrogen forms one bond with no lone pairs, and fluorine forms one bond and has three lone pairs of electrons.
3. Draw the two carbon atoms bonded together with a single bond, then attach the five hydrogen atoms to the carbons to satisfy carbon's four bonds each.
4. Attach the fluorine atom to one of the carbon atoms with a single bond, and assign three lone pairs of electrons to the fluorine atom to complete its octet.
5. Verify that there are no double bonds between the carbon atoms and that no carbon atoms have lone pairs, confirming the correct Lewis structure description.
