Q

positional isomer

A
  • same molecular formula
  • type of structural isomer
  • same backbone/ parent and same branches/functional groups
  • branches/ functional groups are attached to different carbon atoms
  • only the numbers in the names are different

Q

stereoisomer

A
  • same molecular formula
  • atoms are connected to each other in the same way
  • atoms are arranged differently in 3D space
  • would look same if squashed flat (no 3D)
  • same condensed formula
