What is the product when 3 methyl 2-pentene is reacted with HBr?

The major product by far is 3-bromo-3-methylpentane; there may be a small amount of 2-methyl-3-bromopentane.

When 2-pentene reacts with HBr The main product will be?

Accordingly, if hydrogen bromide (or other unsymmetrical reagent) is added to 2-pentene, the reaction would follow to give 2-bromopentane as the predominant product.

Which is the most common product of the reaction between HBr and 3 methyl 2-pentene?

3-bromo 3 methyl pentane will be the major product while 1 bromo 3 methyl pentane will be the minor. This is due to a more stable carbocation being formed.

What happens in the reaction of HBr with 4-methyl-2-pentene?

Reaction of 4-methyl-2-pentene (above) with HBr might, in principle, lead to a mixture of two alkyl bromide addition products. Draw these two alkyl bromides. Do not separate the two structures with a + sign. Reaction of 4-methyl-2-pentene (above) with HBr might, in principle, lead to a mixture of two alkyl bromide addition products.

What is the chemical formula for 4 methyl 2 pentene?

4-Methyl-2-pentene. PubChem CID: 12659. Structure: Find Similar Structures. Chemical Safety: Laboratory Chemical Safety Summary (LCSS) Datasheet. Molecular Formula: C6H12.

Is there a major product of 2-pentene?

Both results agreed within the limit of error (3%) and indicated an equimolar mixture of 2- and 3-bromopentanes […] So, for all intents and purposes, there is no major product. It is not always possible to get a definitive answer based on simplified “rules” and concepts.

What was the product of dehydrohalogenation of 2 pentene?

Wagner and Saytzeff (Ref.1; in German) prepared 2-pentene by dehydrohalogenation of 3-iodopentane. Addition of hydrogen iodide to this pentene yielded a product, which they characterized as the 2-iodopentane.
