Alicyclic
Containing Carbon atoms joined together in a ring that is not aromatic
1 of 20
Aliphatic
Containing Carbon atoms joined together in straight or branched chains
2 of 20
Alkanes
Hydrocarbon homologous series with single C-C bonds. General formula =
3 of 20
Alkenes
Hydrocarbon homologous series with at least one C=C double bond. General formula =
4 of 20
Alkyl Group
A side chain formed by removing a Hydrogen atom removed from an alkane parent chain. Examples : Methyl ( ), Ethyl ( )
5 of 20
Anhydrous
Containing no water molecules
6 of 20
Anion
A negatively charged ion with more electrons than protons
7 of 20
Aromatic
Containing one or more Benzene rings
8 of 20
Atomic Orbital
A region around the nucleus that can hold up to 2 electrons, with opposite spins
9 of 20
Base
A compound that neutralises an acid to form a salt
10 of 20
Binary Compound
A compound containing only 2 elements
11 of 20
Bronsted-Lowry Acid
A species that is a proton, H+, donor
12 of 20
Bronsted-Lowry Base
A species that is aproton, H+, acceptor
13 of 20
Carbocation
An ion that contains a positively charged Carbon atom
14 of 20
Cation
A positively charged ion with fewer electrons than protons
15 of 20
cis-trans Isomerism
A special type of E/Z isomerism where theres 2 non-Hydrogen and 2 Hydrogen atoms around the C=C double bond. The cis isomer (Z isomer) has H atoms on each carbon on the same side. The trans isomer (E isomer) has H atoms on each carbon on diff. sides.
16 of 20
Covalent Bond
The strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms
17 of 20
Dative Covalent Bond
A shard pair of electrons in which the bonded pair has been provided by one of the bonding atoms only. Also known as a coordinate bond
18 of 20
Dipole
A seperation in electrical charge so that one atom of a polar covalent bond, or one end of a polar molecule, has a small positive charge ( ) and the other has a small negative charge ( )
19 of 20
E/Z isomerism
A type of Stereoisomerism in which different groups attach to each Carbon of a C=C double bond may be arranged differently in space because of the restricted rotation of the C=C bond
