Meanings of isopropyl, n-butyl, isobutyl, s-butyl and t-butyl and ...
Jun 11, 2018 · You could attach it from one of the end carbons, in which case we call it "n-butyl." Or you could attach it from one of the inner carbons, in which case we call it "sec-butyl" because the attachment point is a secondary carbon (instead of a primary carbon as it is in n-butyl). (d) There are also two ways to attach the group derived from isobutane.
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
Is tertiary-butyl same as neo-butyl? - Chemistry Stack Exchange
Jan 6, 2021 · By definition neoalkanes have two-times branching of methylgroup at second last carbon. But in no book which I could find, it is not alternatively named as neo-butyl. Is the definition right, or am I
organic chemistry - Why is BuLi a better nucleophile than base ...
Jul 23, 2016 · In Carey, Sundberg Advanced Organic Chemistry it is written: The relative slowness of the abstraction of protons from carbon acids by organolithium reagents is probably also due to the compact
What is the formally correct notation of t-Bu, i-Pr, p-NO2, n-Bu, a …
Mar 25, 2016 · I've also seen them written simply as tBu, iPr, and nBu. They're abbreviations for tert-butyl, isopropyl, n-butyl (straight-chain), and cyclo-hexyl respectively. (Here are links for IUPAC References for non-cyclic and cyclic alkanes.) Substitution points on …
Why n-butanol is not used as a safer alternative to ethanol in the ...
The LD50 of n-butanol adjusted for its intoxicating potency is about 1.5 times that of ethanol. This would mean to me that n-butanol is therefore 50 % safer than ethanol.

organic chemistry - Sec-butyl vs Butyl - Chemistry Stack Exchange
Jun 16, 2018 · This may be resolved by IUPAC Rule A-2.3(ii) which says "The name of a complex radical is considered to begin with the first letter of its complete name," which seems to suggest to me "sec-butyl" is considered to start with "s" and not "b" in this case.
