Butyl group - Wikipedia
Butan-2-yl (sec-butyl) group is chiral. The carbon atom at position 2 is a stereocenter. It has four different groups attached: −H, −CH 3, −CH 2 −CH 3, and −R (the R group is not equal to those three groups). The names of the two chiral groups are: (2S)-butan-2-yl and (2R)-butan-2-yl.
3.3: Alkyl Groups - Chemistry LibreTexts
An alkyl group is formed by removing one hydrogen from the alkane chain. The removal of this hydrogen results in a stem change from -ane to -yl to indicate an alkyl group. The removal of a hydrogen from methane, CH 4, creates a methyl group -CH 3.
Sec-Butyl - (Organic Chemistry) - Vocab, Definition ... - Fiveable
Definition. The sec-butyl group is a branched alkyl substituent with a methyl group attached to the second carbon of a four-carbon chain. It is a structural isomer of the primary butyl group, where the substituent is attached to the terminal carbon.

Nov 10, 2011 · There is no “secondary butane” but there is “sec-butyl” which is when we take a hydrogen off of C2 of butane and stick it on something. Isobutane is the molecule formally called “2-methylpropane” .
Sec-Butyl Group - an overview | ScienceDirect Topics
A Sec-Butyl Group is defined as a steric hindrance group that can be attached to a molecule, providing increased steric bulk and influencing the reactivity and selectivity of chemical reactions. AI generated definition based on: Comprehensive Organic Synthesis (Second Edition), 2014
Naming Butyls - What does n-, s-, t- Mean? - ThoughtCo
Jan 2, 2020 · It is also often labeled as sec-butyl in common names. For systematic names, s-butyl is slightly more complicated. The longest chain at the point of connection is a propyl formed by carbons 2,3 and 4. Carbon 1 forms a methyl group, so the systematic name for s-butyl would be methylpropyl.
2.3: Alkyl Groups - Chemistry LibreTexts
Aug 28, 2019 · Alkanes can be described by the general formula C n H 2n+2. An alkyl group is formed by removing one hydrogen from the alkane chain and is described by the formula C n H 2n+1. The removal of this hydrogen results in a stem change from -ane to -yl. Take a look at the following examples.
Isobutyl vs. Sec-butyl - What's the Difference? | This vs. That
Isobutyl and sec-butyl are two common alkyl groups that are frequently encountered in organic chemistry. These groups differ in their structural arrangement, which leads to distinct chemical and physical properties.
