Some compounds being metamers can also be chain and position isomers.. in this case.. they r metamers along with positional isomers..(frst case.. -O-C is at carbon 1 nd in scnd case it is at carbon 2 of three carbon principal chain..so positional).

Metamers or Position Isomers: Methyl n Propyl Ether and Methyl Isopropyl Ether

Metamers and position isomers are both types of structural isomers. Structural isomers are compounds that have the same molecular formula but different structural arrangements. In the case of methyl n propyl ether and methyl isopropyl ether, they are considered position isomers.

Position Isomers:
Position isomers are structural isomers that differ in the position of functional groups or substituents on the carbon skeleton. In the case of methyl n propyl ether and methyl isopropyl ether, the isomers differ in the position of the alkyl group attached to the oxygen atom.

Methyl n Propyl Ether:
Methyl n propyl ether has the molecular formula C4H10O. In this compound, the methyl group (-CH3) is attached to the oxygen atom, while the propyl group (-C3H7) is attached to the carbon chain. The propyl group is linear, meaning that the carbon atoms are arranged in a straight line.

Methyl Isopropyl Ether:
Methyl isopropyl ether also has the molecular formula C4H10O. In this compound, the methyl group is attached to the oxygen atom, but the isopropyl group (-C3H7) is attached to the carbon chain. The isopropyl group is branched, meaning that the carbon atoms are not arranged in a straight line but rather form a branching structure.

Difference between Methyl n Propyl Ether and Methyl Isopropyl Ether:
The main difference between methyl n propyl ether and methyl isopropyl ether lies in the arrangement of the carbon atoms in the alkyl groups attached to the oxygen atom. In methyl n propyl ether, the propyl group is linear, while in methyl isopropyl ether, the isopropyl group is branched.

Visual Representation:
Methyl n Propyl Ether: CH3-O-CH2CH2CH3
Methyl Isopropyl Ether: CH3-O-CH(CH3)2

Conclusion:
In conclusion, methyl n propyl ether and methyl isopropyl ether are position isomers. They have the same molecular formula but differ in the arrangement of the alkyl groups attached to the oxygen atom. Methyl n propyl ether has a linear propyl group, while methyl isopropyl ether has a branched isopropyl group. These differences in structure lead to different chemical and physical properties for each isomer.
