McMuryy (Kap. 6,1) - kinds of organic reactions

Question 1

Organic reactions can be organized broadly into two ways, which?

Answer 1

• By what kinds of reactions occur
• By how those reactions occur.

Question 2

What kinds of reactions can take place in organic reactions?

Answer 2

• Addition reactions: when two reactants add together to form a single product, with no “left over”.

(H2C=CH2 + H2 –> CH3CH3)

• Elimination reaction: A single reactant splits into two products, often with formation of a small molecule like water (the molecule + water as products).

(CH3CH2Br –> H2C=CH2 + HBr)

• Substitution reactions: when two reactants exchange parts to give two new products.

(CH3Br + KOH –> CH3OH + KBr).

• Rearrangement reactions: When a single reactant undergoes a reorganization of bonds and atoms to yield an isomeric product (Isomers are compounds that have the same molecular formula but different structural arrangements of atoms, resulting in different physical and chemical properties).
