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.

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 …

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

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

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

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.

Jun 16, 2018 · For the structure below, if we use trivial name for complex substituent, do we call it 5-butyl-10-sec-butyltetradecane, or 5-sec-butyl-10-butyltetradecane?

Jan 9, 2018 · In general, for the given substrates (n-butyl chloride, sec-butyl chloride, and tert-butyl chloride), we can make a few observations: $1^\circ$ Substrate (n-butyl chloride): $\mathrm{S_N2}$ is favored because of the much less hindered nature of the primary carbon. The effective rate would primarily be undertaken by $\mathrm{S_N2}$.

Nov 9, 2022 · Water is more polar than acetone, so 80/20 water/acetone is a more polar solvent than 70/30 water/acetone. Since the SN1 reaction has a positively charged carbocation intermediate, more polar solvents are better able to solvate and stabilize this intermed
