IB Chemistry Sub-topic S3.2 Definitions

A carbon bonded to four different groups

Attached groups are the same on the same side of the bond plane

Isomerism that only occurs with bond rotation restriction and communicates symmetry around the bond plane based on group identity

Molecules with different arrangements that require bond breaking and reforming to align

Molecules with different spatial arrangements that can be aligned by bond rotation

Optical isomers that are not mirror images of each other

The groups with the highest atomic numbers are on opposite sides of the bond plane

Isomerism that only occurs with bond rotation restriction and communicates symmetry around the bond plane based on atomic number

Optical isomers that are mirror images of each other

A unique pattern of absorption in the wavenumber region of 1400-400 cm^-1

A method that provides information about the environment of hydrogen atoms

The atom that the hydrogen is attached to and atoms bonded to that atom

A measure of saturation of an organic molecule

A method that shines infrared light on molecules and measure absorption

A method that vaporizes and ionizes a sample molecule, and then deflects its into different fragments with magnetic field

Isomerism where two molecules have the same molecular and structural formuals but are not super-imposable

A device that detects the optical activity of enantiomers

A mixture with equal amounts of enantiomers, which is optically inactive

Produces the splitting pattern on H-NMR due to the influence of Hydrogen nuclei on other neighbouring Hydrogen nuclei

Molecules with the same structural formula but different spatial arrangements

Attached groups are the same on opposite sides of the bond plane

A method that shines X-rays on bonds and uses a sensor to detect the diffraction of the X-rays to measure bond length

The groups with the highest atomic numbers are on the same side of the bond plane
