I apologize, but as an AI text-based bot, I cannot view or access images or external links. However, I can still explain the mechanism for the reaction between 3-methyl-2-pentene and HCl.
The reaction between 3-methyl-2-pentene and HCl is an example of an electrophilic addition reaction. It involves the addition of an electrophile (H+) to the double bond of the alkene.
In this case, the double bond in 3-methyl-2-pentene reacts with HCl, resulting in the creation of a new bond between the carbocation formed and the chloride ion. The reaction proceeds in several steps:
1. Protonation: The alkene acts as a nucleophile and donates its pi electrons to the H+ from HCl. This leads to the formation of a carbocation intermediate.
2. Carbocation rearrangement (if applicable): If there is a possibility for carbocation rearrangement, the carbocation may rearrange to a more stable structure, such as by shifting alkyl groups or forming a resonance structure.
3. Nucleophilic attack: The chloride ion (Cl-) acts as a nucleophile and attacks the positively charged carbon atom in the carbocation intermediate. This forms a new bond between the carbon and the chloride ion.
4. Deprotonation: The remaining hydrogen atom (originally from HCl) is removed by a nearby base (such as water or a chloride ion) to regenerate the catalyst (H+) and produce the final product.
Overall, this reaction converts the double bond in 3-methyl-2-pentene into a single bond with a chlorine attached, resulting in the formation of a chloroalkane.
