What is the difference between reducing a compound using NaBH4, and reducing a compound using H2 and Ni catalyst? Also thank you so much for your videos I really appreciate them :)))
Benzene is very difficult to hydrogenate because doing so dispenses with the stable aromatic system of delocalised electrons. To hydrogenate benzene requires a highly active catalyst and conditions of high temperature and pressure. The Ni catalyst won't do it
Hi at 1:59 can you write H20 and HCl or does it just have to be HCl?
Thank you for these they're very useful for quick organic revision even though I do CIE chemistry
Glad you like them!
at 8:36 it didnt say excess NaOH so can u jus react one of the groups with the NaOH and get a mark?

It’s because reducing agents are specific to functional groups. Got to use the right one to achieve the desired effect. Hope that helps :)
for 9:10 won't we need an AlBr3 catalyst?
No it’s a phenol
Are these CIE questions
why doesnt H2/Ni at 7:30 make benzene to Cyclohexane?

@@MaChemGuy thankyou so much!
