What is the difference between isobutyl and sec butyl

Remember that we use the suffix -yl here because we're referring to an R-group coming off of a molecule. If these were standalone alkanes, we'd use the suffix -ane e. This straight-chain butyl is called butyl, but you might also see it called n-butyl.

This version, which looks a lot like isopropyl, is called isobutyl. Pro-tip: sometimes you'll see this abbreviated as t-bu. Hopefully this quick guide helps!

However, if there is a carbon chain of three carbon atoms and a branch of the methyl group a methyl substituent that occurs at the first carbon atom the carbon atom that is nearest to the R group or the vacant site of the functional group , then this functional group is named as sec-butyl group or secondary butyl group.

Overview and Key Difference 2. What is Isobutyl 3. What is Sec-butyl 4. Isobutyl vs Sec-butyl in Tabular Form 5. Summary — Isobutyl vs Sec-butyl. Isobutyl functional group is a four-carbon alkyl radical or functional group in which a three-membered carbon chain is attached to one methyl group at its second carbon atom.

Therefore, this functional group contains a single methyl branch.
