AI Thread Summary
The reaction of hydrogen cyanide (HCN) with aldehydes generally yields better results than with ketones due to steric strain associated with ketones. When considering the reaction of HCN with an aromatically conjugated aldehyde, such as benzaldehyde (Ph-CHO), the expected yield is lower than that of a standard aldehyde but higher than that of a ketone. This is attributed to the electron-donating nature of the phenyl group, which reduces the electrophilicity of the carbonyl carbon. The presence of resonance in benzaldehyde, which causes electron repulsion, is stronger than the inductive effects seen in ketones, further influencing the reaction yield.

Reaction of HCN with an aldehyde has higher yield than HCN with a ketone due to steric strain around the ketone. Then how about reaction yield of HCN with an aromatically conjugated aldehyde (like Ph-CHO) comparing with the previous two reactions?
What I think:
The yield be lower than just with regular aldehyde and higher than with ketone. Since the phenyl group is Electron donating, thus making the carbonyl carbon less Electrophilic. Tell me if I am right or wrong, thank you.

According to me the yeild should be lower than ketones as in ketones only inductive effect operates but in benzaldehyde resonance occurs.resonance as an electron shift effect is stronger and generates more repulsion
 

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...
