Question

what is the lewis structure for (CH₃)₂SeO with all electron pairs (lone Pair) on all Atoms in the molecles

Answer 1

Step method to draw the Lewis dot structure

Step 1: Find valence e- for all atoms. Add them together. C-4H-1x4=4 Total=8

Step2: Find octet e- for each atom and add them together. C-8H-2x4=8 Total=16

Step3: Gives you bonding e-. Subtract step 1 total from step 2 16-8=8e-

Step 4: Find number of bonds by diving the number in step 3 by 2(because each bond is made of 2 e-) 8e-/2= 4 bond pairs

Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1. 8-8= 0e-=0 lone pairs Use information from step 4 and 5 to draw the lewis structure.

Alternatively a dot method can be used to draw the lewis structure. Calculate the total valence electrons in the molecule. C-4 H-1x4=4 Total=8

Put carbon in center and arrange hydrogen atoms on the sides.Arrange electrons between carbon and hydrogen atoms.
