Chapter 3: Introduction to Organic Molecules and Functional Groups Flashcards
[3.1] The reactive part of the molecule that gives its characteristic chemical and physical properties
Functional group
[3.1] What do you call the unreactive part of the organic molecule that is made of C-C and C-H sigma bonds?
Carbon backbone
[3.2A] What are the two types of hydrocarbons?
Aliphatic and aromatic
[3.2A] What are the three types of aliphatic hydrocarbons, including their general structure and functional group?
- Alkanes: C-C (no FG)
- Alkenes: C=C (FG is double bond)
- Alkenes: C≡C (FG is triple bond)
[3.2A] What is the functional group of aromatic compounds?
Phenyl group
[3.2A] How are carbon atoms classified (primary, secondary, etc.)?
Classified by the number of other carbons directly bonded to them
[3.2A] How are hydrogen atoms classified (primary, secondary, etc.)?
Classified by the type of carbon atom to which they are bonded
[3.2B] Explain what makes C-Z 𝛔 Bonds reactive according to acid-base and electrophile-nucleophile reactions.
> Heteroatom Z
Lone pairs on Z
Heteroatom Z - electronegative and creates a polar bond, making carbon electron deficient
Lone pairs on Z - available for reaction with protons and electrophiles
[3.2B] General structure and functional group of alkyl halides?
R-X
FG: Halo group (-X)
[3.2B] General structure and functional group of alcohols?
R-OH
FG: Hydroxy (-OH)
[3.2B] General structure and functional group of ethers?
R-OR
FG: Alkoxy (-OR)
[3.2B] General structure and functional group of amines?
R-NH2
R2-NH
R3-N
FG: Amino group (-NH2)
[3.2B] General structure and functional group of thiols?
R-SH
FG: Mercapto group (-SH)
[3.2B] General structure and functional group of sulfides?
R-SR
FG: Alkylthio (-SR)
[3.2B] How are alkyl halides and alcohols classified (primary, secondary, etc.)?
Classified by the type of carbon atom to which they are bonded
[3.2B] How are amines classified (primary, secondary, etc.)?
Classified by the number of other carbons directly bonded to them
[3.2C] Explain what makes C=O Bonds (carbonyl groups) reactive according to acid-base and electrophile-nucleophile reactions.
> C=O bond
lone pairs on O
pi bond
C=O bond - polar; makes the carbonyl carbon an electrophile
Lone pairs on O - act as a nucleophile and a base
Pi bond - easily broken
[3.2C] General structure and functional group of aldehydes?
RCHO
FG: -CHO
[3.2C] General structure and functional group of ketones?
RCHR
FG: Carbonyl group (-CHR)
[3.2C] General structure and functional group of carboxylic acids?
RCOOH
FG: Carboxyl group (-COOH)
