2. **(from Review)** Propose a sequence of reagents for the following transformation [Chapter 11, section 11.3] involving changes to the carbon skeleton.### Description and ExplanationThe given sequence diagram illustrates the step-by-step chemical transformation of a hydrocarbon involving carbon skeleton rearrangements, as described in Chapter 11, Section 11.3 of the study material. Below, each step and the corresponding structural change are outlined:1. **Starting Material**: - The first structure is a simple hydrocarbon with the formula \(\ce{CH3-CH(CH3)-CH2-CH3}\).2. **First Transformation**: - The first step involves the introduction of a bromine atom through a substitution reaction, resulting in the compound \(\ce{(CH3)2CBr-CH2-CH3}\).3. **Second Transformation**: - The next step converts the bromoalkane to an alkene via an elimination reaction, yielding \(\ce{(CH3)2C=CH-CH3}\).4. **Third Transformation**: - The alkene then undergoes a reaction that rearranges the carbon skeleton, forming a new structure \(\ce{CH3-CH=C(CH3)-CH3}\).5. **Fourth Transformation**: - Another substitution reaction occurs, reintroducing a bromine atom into the rearranged alkene, producing \(\ce{CH3-CH2-CBr(CH3)-CH3}\).6. **Fifth Transformation**: - Finally, the brominated compound undergoes a nucleophilic substitution where a nitrile group (\(\ce{CN}\)) replaces the bromine, resulting in the final product \(\ce{CH3-CH2-C(CN)(CH3)-CH3}\).### Visualization of TransformationsTo summarize, the sequence of reactions involves the following transformations and chemical reagents:1. **Initial Hydrocarbon State**: \[ \ce{CH3-CH(CH3)-CH2-CH3} \] → (Bromination, \(\ce{Br2}\))2. **Formation of Bromoalkane**: \[ \ce{(CH3)2CBr-CH2-CH3} \] → (Elimination, \(\ce{EtOH}\))3. **
