Transcript text: Which of the following is the correct drawing of resonance? $\mathrm{H}_{3} \mathrm{C}$

Solution

Solution Steps

Step 1: Identify the Resonance Structures

Resonance structures are different ways of drawing the same molecule, showing the delocalization of electrons. The structures must have the same arrangement of atoms but different arrangements of electrons.

Step 2: Analyze Each Option

Option 1: Shows a movement of electrons from a lone pair on oxygen to form a double bond with carbon, and the double bond between carbon and oxygen moving to form a lone pair on the other oxygen.
Option 2: Shows a similar movement of electrons but results in a negative charge on the carbon, which is less stable.
Option 3: Shows a movement of electrons that results in a positive charge on the carbon, which is also less stable.
Option 4: Shows a movement of electrons that results in a negative charge on the oxygen, which is more stable.

Step 3: Determine the Correct Resonance Structure

The correct resonance structure should show the delocalization of electrons without creating unstable charges on the carbon atom. The most stable resonance structures are those that place negative charges on the more electronegative atoms (oxygen in this case).
