Hi,
I am an organic chemistry teacher overseas: in a french speaking area, actually.
I think you’re doing a great job with this site.

Does grignard reagent react with HCN to yield a aldehyde??

No, HCN protonates the Grignard.

yes it surely can..if thr s any othr group other than hydrogen, the one attachd to CN, it leads to formation of ketones..

After 2 years in college and starting to lose some of that adrenaline that i first had, you and your website have given me that extra boost I need. Thank you so much!

I am graduate student in organic chemistry, and I think that your website is quite useful for when I am planning a synthesis or I if I am looking for info a reaction I am little rusty on.

This one is from resonance theory…

Resonance hybrid is considered as the weighted average of the contributing structures. But , in terms of stability , It is treated as the most stable one…more stable than all the resonating structures. Resonating structures have different stabilities…so…when resonance hybrid is treated as an average , It should be placed behind most stable resonating stucture…but why is that not so ?

because in hybrid the electon cloud has larger space to be delocalised……not restricted to any particular p- orbital……so electronic repulsion falls drastically leading to increase in stability…..

Do you know any websites that might be helpful for the mechanism of converting toluene into a tropylium cation? I’m having trouble with the rearrangement once I have my benzyl cation.

I just started Organic Chemistry I and a question has been bugging me since that first class. Oxygen has 6 valence electrons but when drawing a lewis structure to show the bonds, it has 7. Why???
