    What I really want to know though is what happens to the Mg2+ and the Br- and also the H2O? 🤔😩

    • @robochibi
      @robochibi 3 ปีที่แล้ว +5

      The MgBr is actually attached to the O- that was broken but it is not shown in the video. When an acid or hydronium is added than this attacks the MgBr bond and replaces it with a hydrogen thus giving an OH group. Your byproduct would then be a OHMgBr or ClMgBr depending on what you used to remove that MgBr group from the O- group.

    How do you know what side to put your reagent on? I keep thinking that you could choose either or because you’ll still end up with the same answer..? 08:26 I’ve seen others put their reagents on the aldehyde side and they’ve gotten it the answer right.

      When carbon is attached to a more electronegative atom like O of N ..the more electronegative atom attracts the shared pair of electrons from the electron cloud towards itself ..so it develops partial negative charge.

    • @Bdots44
      @Bdots44 4 ปีที่แล้ว

      no nvm, 1 eq of grignard means the reactant is aldehyde or ketone, but the products will always be alcohols for the girgnard reagent. 2 eq of grignard means reactant is ester or acid chloride and the product will be an alcohol with 2 R groups. For 1 eq of grignard that reacts with either aldehyde or ketone, product will also be alcohol but with only 1 R group
