Question

which of these is the correct lewis structure for methanol, ch₃oh? four lewis structure options with circles (radio buttons) next to them, one circled blue

Explanation:

Step1: Recall Lewis Structure Rules

Lewis structures show atom bonding and lone pairs. For \( \text{CH}_3\text{OH} \) (methanol), the structure has a \( \text{C} \) bonded to 3 \( \text{H} \) and 1 \( \text{O} \), and \( \text{O} \) bonded to \( \text{C} \) and 1 \( \text{H} \), with \( \text{O} \) having 2 lone pairs.

Step2: Analyze Each Option

• First option: Check bonding. \( \text{C} \) bonded to 3 \( \text{H} \) and \( \text{O} \), \( \text{O} \) bonded to \( \text{C} \) and \( \text{H} \), with \( \text{O} \) lone pairs. Matches methanol's structure (\( \text{CH}_3\text{-OH} \), where \( \text{C} \) has 4 bonds, \( \text{O} \) has 2 bonds (to \( \text{C} \) and \( \text{H} \)) and 2 lone pairs).
• Second option: Incorrect bonding (e.g., \( \text{H-H} \) bond not in methanol, improper \( \text{C} \) bonding).
• Third option: Incorrect central atom (shows \( \text{O} \) as central, but methanol's central is \( \text{C} \) connected to \( \text{O} \)).
• Fourth option: Incorrect bonding (improper \( \text{C-O} \) and \( \text{H} \) bonding).

Answer:

The first option (the top - most Lewis structure with the unselected circle initially, showing \( \text{H} \) atoms bonded to \( \text{C} \), \( \text{C} \) bonded to \( \text{O} \), and \( \text{O} \) bonded to \( \text{H} \) with lone pairs on \( \text{O} \))
