In the Lewis formula for ClF₃,how many lone pairs are around the central atom? A)0 B)4 C)3 D)2 E)1

Question

Quizplus · Accepted Answer

The central atom in the molecule is sulfur (S). There are two bonds between S and Cl and one bond between S and F. Thus, the total number of bonds around sulfur is three. Since sulfur needs three more electrons to complete its octet, there can be a maximum of three lone pairs around sulfur. However, in the given Lewis structure, there is only one lone pair around sulfur. Therefore, the answer is D, which represents one lone pair.
