Types Of Reactions In Organic Chemistry (chpt. 23) Flashcards
1
Q
Substitution reaction
A
A chemical reaction in which an atom or group of atoms in a molecule is replaced by another atom or group of atoms
2
Q
Mechanism
A
The mechanism of a reaction is the detailed step-by-step description of the overall reaction occurs occurs
3
Q
Chain reaction
A
A reaction that continues on and on because a product from one step of the reaction is a reactant for another step of the reaction
4
Q
Evidence for the reaction of mono chlorination of methane
A
- takes place when exposed to UV light (free radicals involved)
- ethane is found in products (methyl free radicals present and react together to form ethane)
- tetramethyl lead speeds up reaction (only a mechanism involving free radicals would be affected by adding free radicals)
- thousands of chloromethane molecules are formed for every photon of light absorbed (chain reaction)
5
Q
Addition reaction
A
One in which two or more molecules react together to form a single molecule
6
Q
Hydrogenation reaction
A
Involves hydrogen reacting with unsaturated substances ( C double / treble bonds )
