Question

Possible Lewis structures for 6 molecules are shown below. Which figures show correct structures? Correct C: Correct » -- :0: Incorrect » :#-$i-: Incorrect - H-j=c-j-HI :o: Incorrect » H-c-5-11 H Correct :C-S-s-c: Check the numbers of valence electrons - all 6 should be neutral molecules, not ions. Submit Answer Incorrect. Tries 1/10 Previous Tries

Answer 1

For cheeking if "Cheeking if the lewis structure drawn is correct or not one has to Check the number o k the number of electrons around each atom. If there are 8 electrons (octet rule followed) for atoms other than hydrogen.Om Zelections for hydrogen Then the structure is correct. - who are making the bon two electrons which are shared by two atoms which belongs to that atom. 17:77: maring the bond. Lone pain is 2 cectrons which belongs to thal " =c?: - for each carlom 8 electrons (4 bonds la doulle fond, 2 single land x 24 = 8e) F. for each fluorine 8 elecom (I bondt 3 lone pair of ) so, oetet for each atom (all C and all f). =(22+ 3x 2e) = 8e. So the Lewis structure is correct. 9-Fi F. -"Si-F: :F: I-Ö=c=0-H → for C + 4 bond X 24 = 8e 7 All octet fullfilled. for Fal bond X 2e + 3 lone pos'r x 2e = 8e correct ſtructure. for 0 - 2 bond X 2€ + 2 lone pair X 24 = 8 - – for sin 4 bond X2e + 1 = lde Lone paire lp for Fal bond X2e +3 Xpx 2e = 8e y exceeds the octet. Incorrect Structure → for C-5 bond X 2e = 10e -7 exceeds the for oxygen in OH - 3 lond X 2e+ I lpx 2e = 8e octet for oxygen in 2-0 + 1 bond X2e + 3 lpx 2e = 8e Incorrect 1. Structure, - for H - I bond X 2e = 2e - doublet fulfilled for C 4 bond X 2e = 8e 7 Octet fulfilled for s-> 2 bond x 2e + 2 lpx 2e = 8et Correct structure =H --H

7:C1--5-a: + for s 2 hond X2e + 2 6px 2e-8e 7 octet fulfilled for cl l bond X2e + 36px 2e = 8e Correct Structure
