Question

this sketch of a neutral molecule is shaded red or blue wherever the electrostatic potential at the molecules surface isnt zero. what could the charge formula of the molecule be? electrostatic potential map possible chemical formula (click all that apply) cif hf hci cl₂ h₂co

Explanation:

1. Analyze the electrostatic potential map: The map shows a diatomic molecule with a partial positive (blue) and partial negative (red) region, indicating a polar covalent bond (difference in electronegativity between atoms).
2. Evaluate each formula:

• \( \text{ClF} \): Polar (Cl and F have electronegativity difference), diatomic.
• \( \text{HF} \): Polar (H and F, large electronegativity difference), diatomic.
• \( \text{HCl} \): Polar (H and Cl, electronegativity difference), diatomic.
• \( \text{Cl}_2 \): Nonpolar (same atoms, no electronegativity difference), so electrostatic potential would be uniform (not matching the map).
• \( \text{H}_2\text{CO} \): Triatomic (contains 3 atoms: H, C, O), but the map shows a diatomic molecule (two - colored regions, implying two atoms), so \( \text{H}_2\text{CO} \) is eliminated.

The map’s diatomic shape (two - colored spheres) matches \( \text{ClF} \), \( \text{HF} \), and \( \text{HCl} \) (all diatomic, polar), while \( \text{Cl}_2 \) is nonpolar and \( \text{H}_2\text{CO} \) is triatomic.

Answer:

A. ClF, B. HF, C. HCl
