  • organic chemistry - Where does the name ‘aliphatic’ come from . . .
    Funny thing is, "aliphatic" also means "producing fats" Goldbook says: aliphatic compounds Acyclic or cyclic, saturated or unsaturated carbon compounds, excluding aromatic compounds Some definitions exclude alicyclic compounds from the list of aliphatic compounds, but IUPAC doesn't agree, so Note that aliphatic compounds can be saturated or
  • What are the differences and similarities between an aliphatic and an . . .
    Aliphatic compounds Aliphatic compounds are hydrocarbons (wiki, compounds containing only $\ce{C}$ and $\ce{H}$) which are not aromatic An example would be hexane Alicyclic compounds Alicyclic compounds are aliphatic compounds that contain one or more rings An example would be cyclohexene Gallery
  • Converting cyclic compounds to their corresponding aliphatic compounds
    The reaction you want to know about is "Cleavage reaction" in particular oxidative cleavage In this dihydroxylation, if the solution is warm or acidic or too concentrated, oxidative cleavage of the glycol may occur
  • organic chemistry - How to transform an aliphatic primary amine to the . . .
    Could you suggest a reagent or procedure to transform an aliphatic primary amine to the corresponding nitro compound I know this is a bit backwards of a request because the usual procedure is the reduction of nitro groups to their corresponding amine, but there is a need of its electron-withdrawing properties for a subsequent condensation to
  • Aromatic and aliphatic amines - Chemistry Stack Exchange
    The benzyl group is a common protecting group for amines, and can be removed via hydrogenation with a palladium catalyst As for the basicity of the nitrogen, it would be most similar to an aliphatic amine
  • What is an aromatic alcohol? - Chemistry Stack Exchange
    $\begingroup$ Sometimes phenols (OH group connected to the aromatic ring) are not considered to be alcohols, basically because they are much more acidic than aliphatic alcohols When you use such a convention, aromatic alcohols are those in which you have an aromatic ring and a hydroxyl group connected to a sp3 carbon
  • organic chemistry - What is the order of basicity of amines . . .
    Thus, the order of basicity of aliphatic amines should be: primary > secondary > tertiary Now I have a problem with the first line Greater is the stability of the substituted ammonium cation, stronger should be the corresponding amine as a base
  • Perkin reaction for aliphatic aldehydes - Chemistry Stack Exchange
    This wouldn't be the case for aliphatic aldehydes (with no alpha Hydrogen , else self condensation may occur) Also, if the anhydride used has only one alpha Hydrogen (here acetic anhydride has 3 alpha Hydrogen), then the reaction barely proceeds to completion Instead an aldol type product is obtained
  • Reason for the stronger acidic property of phenol than alcohol
    In phenol, pulling the $\mathrm{p}_z$ electrons from the oxygen atom into the ring causes the hydrogen atom to be more partially positive than it is in aliphatic alcohols This means it is much more easily lost from phenol than it is from aliphatic alcohols, so phenol has a stronger acidic property than ethanol
