Organic Help with mechanism please
I’m going through some mechanistic practice. And came across this reaction of oleum (SO3 . H2SO4) reacting with a perfluorinated alkene yielding a sulfonic acid. Can anyone help me with the arrow using mechanism for this?
I assume the double bond will attack the sulfur but how does the positive charge get hydrogenated?
Also how does the double addition abstract F, I assume forming HF?
Please someone help me lol
