Propyl number of carbons
WebbScore: 4.5/5 (29 votes) . Isopropyl has the specific orientation of being attached to a central carbon atom with two CH 3 molecules attached (so in IUPAC naming it can become dimethylethyl), whereas propyl is three carbons all attached in a line branching off the main carbon chain, so it's two CH 2 molecules and one CH 3 molecule. WebbPreparation. Although many organic carbonates are produced using phosgene, propylene and ethylene carbonates are exceptions.They are mainly prepared by the carbonation of the epoxides (epoxypropane, or …
