Reaction Types Flashcards
What’s the 7 main groups of reactions?
Addition, substitution, Elimination, Condensation, Hydrolysis, Oxidation, Reduction
What’s an addition reaction?
A double bond is broken and 2 molecules join to form a single bond.
Usually c=c or c=o
What’s a substitution reaction?
A functional group is exchanged for another one
What’s an elimination reaction?
A double bond is formed when a functional group is removed and released as part of a smaller molecule
What’s a condensation reaction?
2 molecules join and a small molecule is eliminated (normally H2O or HCl)
What’s a hydrolysis reaction?
2 smaller molecules are formed by splitting a larger one with water
What’s an oxidation reaction?
Loss of electrons or gaining oxygen/losing hydrogen
What’s a reduction reaction
Gain of electrons or loss of oxygen/gain of electrons
What are Grignard Reagents used for?
Help Carbon-Carbon bond formation as this is naturally very difficult
How is Grignard reagent made?
Reacting a halogenoalkane in dry ether with magnesium
What’s the method for making carboxylic acid from a Grignard reagent?
1) In dry ether, bubble CO2 in a Grignard reagent
2) Add dilute acid to the solution
What’s the method for making an alcohol from a Grignard reagent?
1) In dry ether, bubble aldehyde/ketone in the Grignard reagent
2) Add dilute acid
