Detailed explanation-1: -Compounds that have the same molecular formula but different chemical structures are called isomers. Remember isomerism is a property between a pair (or more) of molecules, i.e. a molecule is an isomer of another molecule.

Detailed explanation-2: -Hence, isomers with the same molecular and structural formula are called Stereoisomers.

Detailed explanation-3: -Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. That excludes any different arrangements which are simply due to the molecule rotating as a whole, or rotating about particular bonds.

Detailed explanation-4: -There are many organic compounds which have different properties but the same molecular formula. Such type of molecules which have the same molecular formula but different molecular structures are known as isomers of each other and this phenomenon is known as isomerism.

Detailed explanation-5: -Compounds with identical molecular formula but different structures are called structural isomers.
