Destroyer question 8.

Can someone explain why excess Cl2 adds to replace all hydrogens on the alpha carbon of the ketone?

It just says... simply replace H's to Cl in the answers. I am confused why.

Thanks.

anyone?

I was actually wondering the same thing, because when I first did that question I thought it was a mistake by Romano. Under acidic conditions, only one alpha-hydrogen will be replaced by the halogen during halogenation. I think the correct answer should be C. I think basic conditions would be required to arrive at choice B.

I think it has something to do with Cl2 being much, much more reactive than Br2 so instead of replacing just one H, it replaces all of the them...just a guess though
