what type of mechanisims is needed for this?

**Chemical Reaction Overview:**

The image depicts a chemical reaction involving an alkene with the molecular structure:

- 2-methyl-2-butene (\(C_5H_{10}\))

**Reaction Conditions:**

The reactant, 2-methyl-2-butene, is treated with:

- Hydrobromic acid (\(HBr\))
- In a solvent, DMSO (Dimethyl sulfoxide)

**Expected Reaction Mechanism:**
This reaction likely involves an electrophilic addition mechanism where the double bond in the alkene reacts with \(HBr\). Due to Markovnikov's rule, the bromine atom will add to the more substituted carbon atom, resulting in the formation of:

- 2-bromo-2-methylbutane

This reaction is a typical example of the addition of hydrogen halides to alkenes, demonstrating regioselectivity influenced by the stability of the carbocation intermediate. DMSO acts as a solvent, potentially increasing the rate of reaction due to its polar aprotic nature. 

The product and any further specifics of the reaction conditions, such as temperature or time, are not detailed in the image.
