Can anyone please walk me through the mechanism as this question does not make sense to me. I do have some understanding of the general mechanism. The answer is B) but I don't understand how to get there.

The confusing aspect to me, is the structure of the ylide.

How do you know the answer is B? Is that your guess or did you just get the answer from someone/somewhere? Why wouldn't it be D, for example?

You say you know how the Wittig reaction works, can you go through the mechanism with these particular reagents? Maybe we should start out with this: what is the first step of the mechanism? What makes the Wittig reagent so useful?

Also this belongs in the HW section because it's clearly some type of School type question.
 

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...
