Which organic compound among the following is not an isomer of CH3−CO−CH2CH2CH2CH3?
CH3CH=CHCH2CH2CHO
Isomers are the compounds having the same molecular formula but different physical and chemical properties. Compounds A, C and D have the same molecular formula as that of CH3−CO−CH2CH2CH2CH3 with a formula of C6H12O.
But compound B has C6H10O and hence it is not an isomer of CH3−CO−CH2CH2CH2CH3.
