2011年11月10日 · 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” .

Butyl Group - Introduction, Butyl Structure, Preparation and Uses …
The structure of the sec-butyl group is – CH 3 – CH 2 – CH(CH 3) –. The s – denotes secondary because it attaches to the chain’s secondary carbon. In common names, it is also referred to as sec-butyl.
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, −CH3, −CH2−CH3, and −R (the R group is not equal to those three groups). The names of the two chiral groups are: (2 S)-butan-2-yl and (2 R)-butan-2-yl.
Sec-Butyl - (Organic Chemistry) - Vocab, Definition ... - Fiveable
Explain the structural features and key characteristics of the sec-butyl group. The sec-butyl group is a branched alkyl substituent with a methyl group attached to the second carbon of a four-carbon chain. This structural arrangement differs from the linear butyl group, where the substituent is attached to the terminal carbon.

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
2-Butanol - Wikipedia
Butan-2-ol, or sec-butanol, is an organic compound with formula C H 3 CH (O H)CH 2 CH 3. Its structural isomers are 1-butanol, isobutanol, and tert -butanol. 2-Butanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)- (−)-butan-2-ol and (S)- (+)-butan-2-ol.
