30s - Q2
The electron pair in a C - F bond could be considered…
closer to C because Carbon has a lower electronegativity than Fluorine
an inadequate model since the bond is ionic
closer to F because Fluorine has a higher electronegativity than Carbon
closer to C because Carbon has a larger radius and thus exerts greater controlover the shared electron pair
