Question

Stereoisomers have different:

• A. molecular mass
• B. molecular formula
• C. structural formula
• D. configuration

Answer 1

The correct option is D configuration

Isomers having the same structural formula but different relative arrangements of atoms or groups in space or in 3-D are called stereoisomers.
Different spatial arrangement of atoms which characterise a particular stereo isomerism is called configuration.
$\therefore$ Stereo isomers have same molecular formula but different configuration.
