Question

Quizplus · Accepted Answer

Statement 1 is false because 4-oxopentanal contains an aldehyde and a ketone group, not an ether. Statement 2 is false because hemiacetals have both an alkoxy and a hydroxy group on the same carbon, but acetals have two alkoxy groups. Statement 3 is false because cyclic ketone structures are possible, while cyclic aldehydes are rare.
