S3.2 organic chem

same class mean what

same fictional group

homologous series means what

same functional group and general formula that differ by a CH₂.

as homologous series goes up what is shown

increase in physical properties such as boiling point and melting point

Structural isomers

same molecular formula but a different arrangement of atoms

Structural isomers can be further divided into what

chain and functional group isomers.

these are what isomers

Cis-trans

Cis-trans isomers form due to restricted rotation of what

double bond

Cis-trans isomers can only be interconverted by

breaking covalent bonds

Optical isomers have

chiral carbon atom bonded to four different atoms or groups.

enantiomer

non-superimposable mirror images

two enantiomers can be distinguished from each other by

interaction with plane-polarised light.

what kind of bonds does mass spectrometry break

covalent

what causes the GHG absorption of IR

molecular vibrations that cause a change in the molecule's dipole moment,

postion isomers

same formula functional group is in different place

fictional group isomers

same formula , different functional group

chain isomer

same molecular formula but parent chain has different length
