Module 4 Flashcards
(11 cards)
1
Q
What is a homologous series?
A
- a series of organic compounds having the same functional group but with each successive member differing by CH^2
2
Q
What is structural isomerism?
A
- compounds with the same molecular formula but different structural formulae
3
Q
What is homolytic fission?
A
- each bonding atom receives one electron from the bonded pair, forming two radicals
4
Q
What is heterolytic fission?
A
- one bonding atom receives both electrons from the bonded pair
5
Q
What is a radical?
A
- a species with an unpaired electron
6
Q
What does a curly arrow represent?
A
- the movement of an electron pair
7
Q
What are sigma bonds?
A
- bonds formed by the overlap of orbitals directly between the bonding atoms
8
Q
What are pi bonds?
A
- bonds formed by the sideways overlap of adjacent p orbitals above and below the bonding C atoms
9
Q
What is stereoisomerism?
A
- molecules with the same structural formula but different arrangement of atoms in space
10
Q
What is an electrophile?
A
- an electron pair acceptor
11
Q
What is a nucleophile?
A
- an electron pair donor, attracted to low electron density
