3-methyl-1-butene + br2

Electrophilic addition of Br2 to isoprene yields 3,4-dibromo-3-methyl-1-butene (21%) over 3,4-dibromo-2-methyl-1-butene (3%) product. The mechanism involves the attack of pi-electrons of the isoprenen onto the electrophilic end of Br2 molecule to generate a tertiary carbocation as the major intermediate

The unsaturated aliphatic hydrocarbons, such as 2-METHYL-1-BUTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen.

Now that MArk B Fischer has covered the structural difference, I wonder if you might have been asking about how to tell which is which, assuming you have some of each, or how to tell which one you have, if you’re given one unlabelled. IR does have The major product by far is 3-bromo-3-methylpentane; there may be a small amount of 2-methyl-3-bromopentane. The structure of (E)-3-methylpent-2-ene is According to Markovnikov's rule, the "H"^+ from "HBr" will add to "C-2" of the alkene and form a 3° carbocation at "C-3". The "Br"^- will add to "C-3" and form 3-bromo-3-methylpentane There may be a small amount of product formed when the "H 3-Hydroxy-3-methyl-1-butene - chemical information, properties, structures, articles, patents and more chemical data.
