Draw the product obtained by heating each pair of ketones in a basic solution. Part A In the reaction scheme, two compounds react. The line-angle structure of the first compound shows a four-membered chain consisting of a line terminus, a segment of two vertices, and a line terminus. There is a double bond between the first terminus and the first vertex (from left to right) and an O atom double-bonded to the second vertex. The second compound is a six-vertex ring, with an O atom double-bonded to the first and the third ring vertices and a CH3 group attached to the second vertex.
