Secondary butyl radical
Web10 Nov 2011 · You can replace an H on C-1 (or C-3 or C-4) with OH, in which case you get 2-methyl-1-propanol (“isobutanol”). Or you can replace an H on C-2 with OH, and get 2-methyl-2-propanol (“t-butanol”). Those are the only two ways to do it! This applies to other groups too. So if we used Cl instead of OH, we’d have n-butyl chloride, s -butyl ... Websecondary and(muchmoreslowlypropagating) tertiaryradicals.

WebThese radicals, which are molecular fragments having an unpaired electron, are known as alkyl groups. The names of the alkyl groups are formed by substituting the suffix -yl for -ane in the names of the alkanes from which they are derived. ...

WebRelative Stabilities of Alkyl Radicals (a) A secondary isopropyl radical is more stable than a primary n-propyl radical by 12 kJ mole − 1. (b) A tert-butyl radical is 9 kJ mole − 1 more stable than a secondary isopropyl radical, but the stabilities of the primary n-propyl and isobutyl radicals are the same.

In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C4H9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n-butane can connect in two ways, giving rise to two "-butyl" groups: If it connects at one of the two terminal … See more According to IUPAC nomenclature, "isobutyl", "sec-butyl", and "tert-butyl" used to be allowed retained names.
