Tin, HCl purpose

Is the point of using Sn (s) and hcl during the conversion of nitrobenzene to analine to donate electrons? Why else is this needed? Thanks guys much love.

Hey sport, I don't think we need to know this for the mcat, aromatic stuff shouldn't be on there. Whenever I see metal catalyst in organic though, I think electron transfer.

Sn/HCl is used to reduce nitro groups to amines. That's the only time you'll see it in your typical intro course sequence. Probably not so important for the MCAT.
