Question

Compounds having the same molecular formula but different structures are called:

• A. Isotopes
• B. Isobars
• C. Isotones
• D. Isomers

Answer 1

The correct option is D Isomers

An isomer is a molecule with the same molecular formula as another molecule, but with a different structure. Isomers contain the same number of atoms of each element, but have different arrangements of their atoms. Isomers do not necessarily share similar properties, unless they also have the same functional groups.Some examples are -

Butane and Isobutane
