- Meanings of isopropyl, n-butyl, isobutyl, s-butyl and t-butyl and . . .
(d) There are also two ways to attach the group derived from isobutane You can attach it from one of the end carbons, in which case we call it an "isobutyl" group, or you can attach it from the center carbon, in which case it's "t-buty" or "tert-butyl" for "tertiary" butyl because the attachment carbon is a tertiary carbon
- organic chemistry - Difference between isopropyl and isobutyl . . .
isobutyl where branches define the common name as well In the end my question is: What is the logic of using iso- prefix (especially in those cases), and how can i know when to use it? p s- if you know the answer to my question, it is mostly appreciated to state your source of answer!
- reaction mechanism - What would be the major product of isobutyl . . .
That carbocation might not be isobutyl cation You should be able to see that such a cation would rearrange to the more stable, tertiary, tert-butyl cation with a facile hydride shift You should identify the major product accordingly Carbocation rearrangement is a significant issue with Friedel-Crafts alkylation
- nomenclature - t-butyl VS s-butyl - Chemistry Stack Exchange
In the IUPAC system the common names for t-butyl and s-butyl are still accepted Usually the "t" from tert- and the "s" of sec- is not included in the alphabetic ordering of substituents If you have
- When to use iso and sec while naming compounds in alkyl halides?
According to the current version of Nomenclature of Organic Chemistry – IUPAC Recommendations and Preferred Names 2013 (Blue Book), the prefixes “isobutyl” and “sec-butyl” etc are no longer recommended (“isopropyl” is still retained, but only for general nomenclature)
- organic chemistry - How are t-butyl substituents named according to . . .
Other non-systematic prefixes have fallen from favour, most notably isopropyl, sec-butyl, and isobutyl The preferred prefixes are respectively propan-2-yl, butan-2-yl, and 2-methylpropyl The preferred prefixes are respectively propan-2-yl, butan-2-yl, and 2-methylpropyl
- organic chemistry - Can methyl shift occur for isobutyl cation . . .
A simple methyl shift will not get you from secondary to tertiary butyl cation You need to combine it with a hydride shift in the opposite direction
- reference request - Is isobutyl chloride or ethyl chloride more . . .
Compare the rate of $\\mathrm{S_N1}$ reaction in the following compounds: We see that both compounds form primary carbocations However, there is more hyperconjugation in the second compound as comp
