ohh that's fine


Can you explain to me why HCN cant undergo reaction?


The "why" would have to be conjecture. I know that HCN does not react with alkenyl groups.

The first step in the mechanism is pi electrons moving to the partially positive atom of the reagent, creating a carbonium ion and an anionic group.

Maybe the similar electronegativity between carbon and hydrogen prevents an adequate charge separation on the H-C bond?

It's true that HCN is a very weak acid whereas HBr is strong.

Well that doesn't make sense to me but I am happy that I know the fact HCN don't react with an alkene

thanks, you helped a lot

My Chemistry revision session ends here, Will do rest of work tomorrow

Spoiler



I thought I did good.
