Introduction to Organic chemistry
Define Homologous Series
A series of organic compounds with the same functional group with each successive member differing by CH2
Define functional group
An atom or group of atoms responsible for the characteristic chemical reactions in a compound.
Define empirical formula
The simplest whole number ratio of all the atoms of each element present in a compound
work out the empirical formula of a compound with mass of 23.3% magnesium, 30.7% sulfur and 46.0% oxygen.
MgSO3
What is the product formed in heterolytic fission.
positive and negative ion
(anion and cation)
Define heterolytic fission
When a covalent bond breaks one bonding pair (usually the most electro negative) receives a pair of electrons forming a negative ion, the bonding atom that loses a pair of electrons forms a positive ion.
What is a radical
A high energy unpaired electron.
Define a curly arrow
A curly arrow shows the flow of an electron pair.
What is a 'fishook curly arrow'
A fishook curly arrow represents the movement of a single electron.
What are the products formed in heterolytic fission.
2 radicals.
Define homolytic fission
When a covalent bond breaks each bonding pair receives one electron forming 2 radicals.
Rank the strongest intermolecular forces from weakest to strongest.
1. LDFs
2. Permanent dipole dipole.
3. Hydrogen bond
