7. Show the reagents that would be necessary to carry out each transformation and any major products that wouldbe formed in the intermediate stages. (You may have to use reactions from the last test material)2-methylpropane2-methylpropene

In the given transformation, we are addressing a chemical reaction that converts 2-methylpropane (isobutane) into 2-methylpropene (isobutylene) through a process known as dehydrohalogenation. This type of reaction is essential in organic chemistry, as it involves the removal of a hydrogen atom and a halogen atom from a molecule to form a carbon-carbon double bond.The transformation you're describing involves converting 2-methylpropane (also known as isobutane) into 2-methylpropene (isobutylene). This can be achieved through the elimination reaction, which is typically carried out with strong bases.Here's the reaction and the necessary reagents:1. Dehydrohalogenation of 2-Methylpropane:2-Methylpropane (isobutane) can be dehydrohalogenated to produce 2-methylpropene (isobutylene). This reaction involves the removal of a hydrogen atom and a halogen atom (typically a bromine or chlorine) from 2-methylpropane. Reagents:Strong base like sodium ethoxide (NaOEt) or potassium tert-butoxide (t-BuOK). Reaction:2-Methylpropane --------> 2-Methylpropene + HX (where X is the halogen) The reaction mechanism involves the removal of a hydrogen atom and the halogen atom from adjacent carbon atoms, leading to the formation of a carbon-carbon double bond in 2-methylpropene.Please note that the specific base and conditions may vary based on the reaction conditions and the desired product yield, and this reaction is often carried out in an anhydrous solvent under carefully controlled conditions. Additionally, you might need to add an appropriate halogen source like HBr or HCl for the dehydrohalogenation step.The intermediate stages involve the breaking of the C-H and C-X (X is the halogen) bonds in 2-methylpropane, followed by the formation of a C-C double bond in 2-methylpropene. These stages are typically not isolated as separate compounds but are part of the reaction mechanism.
