Question

22) Which of the following Lewis structures would be an incomplete octet? A) NF3 B) SO2 C) BCI3 D) CF4 E) SO32- 23) Which of the following has the bonds correctly arranged in order of increasing polarity? A) Be-F, Mg-F, N-F, O-F BO-F, N-F, Be-F, Mg-F C) O-F, Be-F, Mg-F, N-F E) Mg-F, Be-F, N-F, O-F 24) Order the elements S, Cl, and F in terms of increasing atomic radii. A) S, Cl, F B) CI, F, S C) F, S, C D) F, CI, S E) S, F, C 25) Of the following elements, A) O ?) ? C) B D) Na E) S has the most negative electron affinity

Explanation / Answer

Ans 22 : C) BCl3

The central atom B in the compound is bonded to three chlorine atoms , so the bonding electrons become 6. There are no lone pairs over the central atom.

So the total number of electrons = 6.

This forms an incomplete octet.
