Question
Consider the molecules $BF_3$, $NF_3$, and $NH_3$. Which of the following statements are CORRECT based on electronegativity and related periodic properties?
Answer: A,B,C,D
💡 Solution & Explanation
All statements correctly apply electronegativity. In A, F pulls density, increasing B's acidity. In B, F withdraws electron density, making N's lone pair less available for donation compared to H (which donates via induction). In C, N-F bond vectors point towards F (away from lone pair), whereas N-H vectors point towards N (reinforcing lone pair). In D, EN decreases down group 15, so P < N.
