Which of the following carbocations would be expected to rearrange? Check all that apply. Check all that apply. A line-angle formula shows a ring with six vertices, a CH3 group attached to the first vertex, and a plus charge at the first vertex. A line-angle formula shows a ring with six vertices, a CH3 group attached to the first vertex, and a plus charge at the second vertex. A line-angle structure has three carbon atoms in the chain with two CH3 groups attached to the first carbon, a CH3 group attached to the second and the third carbon atoms, and a plus charge at the second carbon. A line-angle structure has two carbon atoms in the chain with a CH3 group attached to both carbon atoms and a plus charge at the first carbon. A line-angle formula shows a ring with six vertices, a CH3 group attached to the first vertex, and a plus charge at the fourth vertex. A line-angle structure has two carbon atoms in the chain with two CH3 groups attached to the first carbon, a CH3 group attached to the second carbon atom, and a plus charge at the second carbon.
