What Is the Major Resonance Contributor of This Organic Molecule?

AI Thread Summary
The discussion centers on determining the most significant resonance contributor for a given molecular structure. Participants analyze the implications of a double bond migrating to a different position within the molecule, particularly in relation to a carbon atom. There is a consensus that the double bond is likely to shift to the lowest energy configuration, which would involve the migration of a lone pair from an oxygen atom to form a double bond, resulting in the creation of an oxonium ion. This highlights the importance of considering resonance structures and their stability in understanding molecular behavior.

can someone help me with this question?


Draw the most important resonance contributor of the following structure?

if its to small

looks like that double bond will have to jump to the other you know where
 
unfortunately I don't below the c atom?
 
you'll probably get a migration of the double bond to the lowest bond and then migration of a lone pair from oxygen to form a double bond and make an oxonium ion
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
