Butyl Group - Introduction, Butyl Structure, Preparation and Uses …
The primary distinction between isobutyl and sec-butyl is that the isobutyl group has a branched structure at the second carbon atom of the carbon chain, whereas the sec-butyl group has a branched structure at the first carbon atom of the carbon chain.

For example, there are two structural isomers with the molecular formula C3H7Br. In one of them the bromine atom is on the end of the chain, whereas in the other it’s attached in the middle. If you made a model, there is no way that you could twist one molecule to turn it into the other one.
Butyl group - Wikipedia
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, 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:

2011年11月10日 · Isobutane is the molecule formally called “2-methylpropane” . If we take a hydrogen from one of the methyl groups of isobutane and stick it on something, it is often called, “isobutyl” . For example, isobutyl chloride.

2019年8月28日 · 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.
Illustrated Glossary of Organic Chemistry - Isobutyl group
Iso butyl (iso butyl group): A portion of a molecular structure equivalent to isobutane (2-methyl propane) minus one hydrogen atom from carbon one.

2024年9月30日 · If you imagine removing a hydrogen atom from an alkane, the partial structure that remains is called an alkyl group. Alkyl groups are not stable compounds themselves, they are simply parts of larger compounds and are named by replacing the -ane ending of the parent alkane with an -yl ending.

The prefix "iso" implies that the connection ends with a (CH 3) 2 CH- group. With butyl straight-chain alkyl groups there is the possibility of a connection on the second carbon from the end of the chain. These alkyl groups are given the prefix " Sec.
