The Lewis structure for each of the given ions and molecules is to be explained. Concept introduction: The structure used to show the bonding between the atoms and a lone pair of electrons of the molecule is known as Lewis structure. The rules for drawing the Lewis structure areas follows: The skeletal structure of the compound is drawn, in which the element with the lowestelectronegativity is placed as thecentral atom, which is surrounded by the substituent atoms. The total number of valence electrons for the compound is determined. Subtract two electrons for each bond in the skeletal structure from thetotal number of valence electrons to know the remaining number of electrons. Complete the octet of each terminal atom by placing a pair of electrons from the remaining electrons. If any of the electrons are remaining after completing the octets of the terminal atoms, place the remaining electrons as a pair on the central atom.

Students have asked these similar questions

(a) Describe the molecule xenon trioxide, XeO3, using four possible Lewis structures, one each with zero, one, two, or three Xe—O double bonds. (b) Do any of these resonance structures satisfy the octet rule for every atom in the molecule? (c) Do any of the four Lewis structures have multiple resonance structures? If so, how many resonance structures do you find? (d) Which of the Lewis structures in (a) yields the most favorable formal charges for the molecule?

Draw the Lewis structures for each of the following ions or molecules. Give the number of electrons in each species. Remember to enclose ion s in square brackets with the charge as a superscript outside the right bracket. (a) SO 2 (b) XeO 2 F 2 (Xe is the central atom) (c) ClF 3 (d) ClO 2 F (Cl is the central atom) (e) BrO 4 -

For the next compounds/ions, draw two (2) appropriate Lewis structures. One structure must obey the octet rule and the other structure must be a non-octet obeying structure (octet deficient or octet expansion). Be sure to indicate which structure is the “best” structure and explain your choice formal charge arguments and any other points you deem important. (a) BeCl2 (b) POF3 (c) SO42−
