WebH2 (excess) Pt or Pd or Ni: Note: Catalytic hydrogenation of alkene π bonds is stereospecific with syn addition: H2 (excess) Pt or Pd or Ni: Note: Catalytic … WebIt reduces everything, including the C=C bond. If you add the LiAlH4 slowly to the aldehyde, the aldehyde is always in excess. The relatively small amount of LiAlH4 present at any one time will reduce the most active groups (COOH and CHO) first. Once they have been reduced, you have only an isolated C=C bond remaining, and LiAlH4 does not ...

WebApr 29, 2024 · The reaction with $H_2/Pd$ is one of the ways to reduce alkenes to alkanes. This takes place over the Palladium surface which has $H$ adsorbed on it. Hence we can think of cis addition in this case. It is … WebFor example, one mole of cyclohexene reacts with one mole of hydrogen to produce one mole of cyclohexane: but one mole of 1,4-cyclohexadiene reacts with two moles of hydrogen to form one mole of cyclohexane: A chemist would say that cyclohexene reacts with one equivalent of hydrogen, and 1,4-cyclohexadiene reacts with two equivalents of hydrogen.
