CH2S Lewis Structure Concepts

The video tutorial explains how to draw the Lewis structure for CH2S. It begins by calculating the total number of valence electrons, which is 12. The carbon atom is placed in the center, with hydrogen atoms on one side and sulfur on the other. Initial bonds are formed by pairing electrons between atoms. After distributing electrons to complete the octet for sulfur, it is noted that carbon lacks a full octet. To resolve this, a double bond is formed between carbon and sulfur, ensuring both have complete octets. The tutorial concludes with a review of the final structure.

Why do we need to adjust the electron distribution around sulfur?

• To increase the number of bonds

• To complete the octet for sulfur

• To make sulfur more reactive

• To reduce the number of electrons

What is the issue with the initial electron distribution around carbon?

• Carbon has too many electrons

• Carbon has only six valence electrons

• Carbon is not bonded to hydrogen

• Carbon is not bonded to sulfur

What is the purpose of forming a double bond between carbon and sulfur?

• To complete the octet for carbon

• To increase the molecule's stability

• To make sulfur more electronegative

• To reduce the number of valence electrons
