Dear Haritha
Compounds having the same molecular formula but different number of carbon atoms ( alkyl groups) on either side of functional group ( i.e., -O-,-S-, -NH-, -C(=O)-) are called metamers and the phenomenon is called metamerism. metamerism occurs amongst the members of the same homologus family.For example,
CH3CH2-O-CH2CH3 is metamer of CH3-O-CH2CH2CH3 OR CH3-O-CH(CH3)2
CH3CH2COCH2CH3 is metamer of CH3COCH2CH2CH3 OR CH3COCH(CH3)2
It may be noted that metamers may also be position isomers, e.g., pentan-2-one and pnetan-3-one may be regarded as position isomers as well as metamers.
All the best.
