Functional Groups Pt. 2 Flashcards
A specific structural arrangement of atoms or bonds that imparts a characteristic reactivity to the molecule.
Functional Group
are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties.
Functional groups
in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids.
Functional groups
Functional groups include:
hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and
sulfhydryl.
- Only carbon and hydrogen
- All single bonds
alkanes
What should you call cyclic hydrocarbons made up of just single bonds?
Cycloalkanes
Natural source of alkanes
- natural gas
- petroleum
- coal
- Only carbon and hydrogen
- A carbon to carbon double bond
alkenes
What should you call a molecule with two C=Cs?
diene
is used in welding torches because it burns at high temperature
Ethyne (acetylene)
Many alkynes are of biological interest
- Capillin
- Dactylyne
- Ethinyl estradiol
is an antifungal agent found naturally
Capillin
is a marine natural product
Dactylyne
is a synthetic estrogen used in oral contraceptives
Ethinyl estradiol
is the simpest alkyne
acetylene
it is used in blow torches and as a precursor for the synthesis of more complex alkynes
acetylene
histrionicotoxin
which cna be isolated from South American frogs and is used on poison-tipped arrows by South American tribes
a halogen (F, Cl, Br, I) replaces the hydrogen of an alkane
alkyl halides
halogen
F, Cl, Br, I
In alkyl halides, a _____________ replaces the hydrogen of an alkane
halogen (F, Cl, Br, I)
uses of alkyl halides
- dry cleaning solvents
- degreasing solvents
- paint stripper
- synthetic intermediates in idustry and the lab
sources of alkyl halides
- reactins of alkaswith halogens
- nature, for instance halomon
- Only one oxygen
- Has an O-H group
- Can classify as 1º/2º/3º according to position of O-H group on carbon skeleton
alcohols
Why are short-chain alcohols so soluble in water?
They can form hydrogen bonds with H2O molecules
