Flashcards in Pack 2A definitions Deck (14):
1

hydrocarbons

organic compounds that contain hydrogen and carbon only

2

saturated hydrocarbon

hydrocarbon with single bonds only

3

unsaturated hydrocarbon

hydrocarbon containing carbon to carbon multiple bonds

4

aliphatic hydrocarbon

hydrocarbon with carbon atoms joined together in straight or branched chains

5

alicyclic hydrocarbon

hydrocarbon with carbon atoms joined together in a ring structure

6

functional group

the part of the organic molecule responsible for its chemical reactions

7

homologous series

a series of organic compounds with the same functional group but with each successive member of the group differing by CH2

8

Alkanes

the homologous series with the general formula CnH2n+2

9

Nomenclature

a system of naming compounds

10

alkyl group

an alkane with a hydrogen atom removed e.g. CH3, C2H5
an alkyl group is often shown as 'R'

11

general formula

the simplest algebraic formula of a member of a homologous series. e.g. alkanes ---> CnH2n+2

12

displayed formula

shows the relative positioning of the atoms in a molecule and the bonds between them

13

structural formula

the minimal detail for the arrangement of atoms in a molecule

14

skeletal formula

a simplified organic formula, with hydrogen atoms removed from alkyl chains, leaving just a carbon skeleton and associated functional groups
