Correct order of electronegativity of and is:
Correct order of electronegativity of \( N, P, C \) and \( S i \) is:
- A. \( N<P<C<S \) i
- B. \( N>C>S i>P \)
- C. \( N=P>C=s i \)
- D. \( N>C>P>S i \)
Step-by-step solution
Electronegativity increases across a period and decreases down a group. In period 2, N (3.04) > C (2.55). In group 14, C > Si (1.90); in group 15, N > P (2.19). Comparing across, C (2.55) > P (2.19). Thus the order is N > C > P > Si.
