how do you reduce a benzene ring to a cyclohexane?

[BoneMental]

Is it possible to do? What are the various ways?

Can't you use Pt/H2? Or Ni/H2? I tried looking this up on google and all I got was some weird forum in Britain....

yes, it's called hydrogenation. Just about any Ochem textbook should have clear examples on this.

Pt/h2 and Pd/h2 are the common ones, there's others like Lindlar that take triple bonds to double bonds.

Thanks dude! I thought so, but I just wanted to make sure.

Be careful on this one. If you simply add H2/Pt like with an alkene, benzene doesn't react due to its stability (since it's aromatic). The rxn still needs a catalyst (Pt, Pd, Ni, etc.) but only works if the pressure of H2 is really high (like 1500 psi).

you use H2 Rh/C catalyst. I don't believe you need to know this for the MCAT though. Aromatics are no longer an official AAMC topic
