Question

do ketones show both position isomerism and metamerism ?

Answer 1

Answer:

Metamerism is type of isomerism is due to the difference in the nature of alkyl groups attached to the polyvalent atoms or functional group. Metamers always belong to the same homologous series. Compounds like ethers, thio-ethers ketones, secondary amines, etc. show metamerism.

Thus statement is true.

Answer 2

Answer:

Ketones show both metamerism and positional isomerism simultaneously. ... .

Explanation:

• Aromatic aldehydes and ketones having 5 or more carbon atoms can exhibit position isomerism. Example: CH3−CH2−CO−CH2−CH3 and CH3−CO−CH2−CH2−CH3 are position isomers.
• ketones show metamerism because ketoneis a bivalent functional group and as we know that only polyvalent functional groupsshows metamerism and is the ketone. Yes, ketones do show metamerism in the case of mixed ketones. ... -O-,-NH-,-S-,and carbonyl group ex ketone shows metamerism.
