WebFirst, NaBH4 is not so reactive and the reaction is usually carried out in protic solvents such as ethanol or methanol. The solvent has two functions here: 1) It serves as the source of a proton (H +) once the reduction is complete. 2) The sodium ion is a weaker Lewis acid than the lithium ion and, in this case, the hydrogen bonding between the ... WebMECHANISM FOR REACTION OF ALKENES WITH H3O+ Step 1: An acid / base reaction. Protonation of the alkene to generate the more stable carbocation. The pi electrons act as a Lewis base. Step 2: Attack of the nucleophilic water molecule on the electrophilic carbocation creates an oxonium ion. Step 3: An acid / base reaction.

"WebWell. compared to an aldehyde with one alkyl group, a ketone has two. Not only does sterics make ketones harder to attack, the two alkyl groups (e- donating) diminishes the partial positive charge character of the carbonyl. The sizes of the chains matter little as the carbonyl group is trigonal planar. Comment ( 3 votes) Upvote Downvote Flag more " - Ketone reacts with hydronium
