Question

Consider the following statements about structural isomerism.

(1) Chain isomers differ in the arrangement of the carbon skeleton.

(2) Metamers contain the same functional group.

(3) Tautomers are readily interconvertible structural isomers.

Which of the above statements are correct?

TestHub · Accepted Answer

Statement (1) is correct : chain isomerism is exactly a difference in the carbon skeleton (e.g. n-butane and isobutane). Statement (2) is correct : metamers differ in the alkyl groups around the same functional group (e.g. diethyl ether and methyl propyl ether). Statement (3) is correct : tautomers (e.g. keto and enol forms) interconvert readily. All three statements are correct.
