MacBook Air TOTAL DRAW A LEWIS STRUCTURE (INCLUDE ALL NON-ZERO FORMAL CHARGES) PART A CONTINUED). XeF SO2 Brfs REPORT #10: LEWIS STRUCTURES & MOLECULAR MODELS CH2Br2 BH

Answer 1

Ans:- 1 X e F4 Lewis structure Total valence electrons = 1 (8 es from 'X) + 4 (t es from 'f') = 8+104) - 36 f . fi Ft * Total number of o bonds = 4 *Molecular geometry: Square planar * Total number of a bonds=0 * Hybridisation :sp3d² * Xefa is a non-polar because it is symmetrical and no diopole moment. (dipolemoment (10 =0) . Non-polar. 2) 500² Lewis structure Total Valence electrons = 16es from 'S') + 4 (6 es from '0') tzē = 6+24+2 = 32 es. :0— 5— 0: b-10- Total number of o bonds=4 ; Molecular. Tetrahedral Geometry Total number of a bonds=2; Hybridisation : SPS * sout is non-polar because the dipoles canced each other and has no dipole moment.

5) Bla- Lewis structure Total Valence es = 1(30 from 'B') + 3 (1 ē komit") = 3+3 = ber HEB:1 con i Total no. of a bonds = 3 Total no. of a bonds = 0 * BH₂ is non-polar TH Molecular Geometry - Trigonal planas Hybridisation in sp2 due to cancellation of all dipples. I
