1.	(Propanal, Propanone) and (Pentane-3-one, Pentane-2-one) represent the isomerism of which type respectively?
Answer» Metamerism, Position Metamerism, Functional group Functional group, Chain isomerism Functional group, Metamerism Solution :(i) `{:("Formula",CH_(3)CH_(2)CHO,CH_(3)COCH_(3)),("Name","Propanal","Propanone"),("MF",C_(3)H_(6)O,C_(3)H_(6)O),("Group","aldehyde","ketone"):}` They have same MF but DIFFERENT functional group and functioal group isomerism (II) Pentane-3-one `CH_(3)CH_(2)COCH_(2)CH_(3)` Pentane-2-one `CH_(3)COCH_(2)CH_(2)CH_(3)` `therfore` They are METAMERS
