Vedclass · Answer

(C) Rearrangement involving a change in the carbon skeleton occurs when an alkyl group or aryl group shifts to a carbocation center.In option $(b)$,$CH_3-CH_2-CH_2^{\oplus}$ (a $1^{\circ}$ carbocation) undergoes a $1,2-H^{\ominus}$ shift to form $CH_3-CH^{\oplus}-CH_3$ (a $2^{\circ}$ carbocation),but the carbon skeleton remains the same.In option $(c)$,$CH_3-CH(CH_3)-CH_2-CH_2^{\oplus}$ (a $1^{\circ}$ carbocation) undergoes a $1,2-CH_3^{\ominus}$ shift to form $CH_3-C^{\oplus}(CH_3)-CH_2-CH_3$ (a $3^{\circ}$ carbocation). This shift changes the carbon skeleton from a branched chain to a different branched structure,which is the correct type of rearrangement.

In which of the following reactions does a rearrangement take place with a change in the carbon skeleton?
