How many metamers of 3-pentanone are possible? Write their structures

1.	How many metamers of 3-pentanone are possible? Write their structures and IUPAC names. Can these be regarded as position isomers as well ?
Answer» Solution :Two metamers (I and II) of 3-pentanone are POSSIBLE. `underset("3-Pentanone")(CH_(3)CH_(2)-OVERSET(O)overset(\|\|)(C)-CH_(2)CH_(3)) "" underset("2-Pentanone (I)")(CH_(3)-overset(O)overset(\|\|)(C)-CH_(2)CH_(2)CH_(3))``{:(""O""CH_(3)),("\|\|""\|"),(CH_(3)-C-CH-CH_(3)),("3-Methyl-2-butanone (II)"):}` Both these can ALSO be regarded as position isomers of 3-pentanone because they differ in the position of the KETO group.
