- Meanings of isopropyl, n-butyl, isobutyl, s-butyl and t-butyl and . . .
I am having a hard time learning organic chemistry because I cannot understand the meanings of isopropyl, n-butyl, isobutyl, s-butyl and t-butyl There is no proper explanation given in my book about them
- organic chemistry - Difference between isopropyl and isobutyl . . .
For instance, n-propyl and isopropyl are named according to the carbon atom which has a lack of hydrogen The same goes for isobutyl where branches define the common name as well What is the logic of using the prefix “ iso- ” (especially in those cases), and how can I know when to use it? Please cite authoritative sources
- 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
- When to use iso and sec while naming compounds in alkyl halides?
sec 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) Preferred IUPAC names of alkyl halides are formed using substitutive nomenclature, i e using the
- organic chemistry - Can methyl shift occur for isobutyl cation . . .
Sec-butyl cation maybe? Isobutyl would have the branched methyl group already and thus would merely undergo hydride shifting
- 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
- What is the formally correct notation of t-Bu, i-Pr, p-NO2, n-Bu, a-HCl . . .
isobutyl: iBu sec -butyl: s -Bu tert -butyl: t -Bu However, the ACS Style Guide recommends different abbreviations: isopropyl: i -Pr isobutyl: i -Bu sec -butyl: sec -Bu tert -butyl: t -Bu Furthermore, authors may create their own abbreviations, but any abbreviations not included in the recommendations shall be defined clearly when they are used
