Chapter 11 Flashcards
Notability
Which are the most utilized complex structure?
Bond line
Every carbon atom has
4 covalent bonds
Organic compounds are based on
Carbon
Carbon can form
Isomers with many different compunds
Isomers are
Different compounds with the SAME MOLECULAR FORMULA
Isomers can differ either by
Atomic connectivity or in stereochemistry
Hydrocarbons are molecules composed entirely of
Carbon & Hydrogen atoms
Found in straight chains w/or without branches
Saturated hydrocarbons/compounds are
Single bonded carbon chains with all available carbon bonds attached to hydrogen
(Single covalent bonds)
Less reactive
Blue Flame
Unsaturated hydrocarbons have
1 or more double or triple bonds between carbon atoms
Sooty flame
Alkanes contain only
Single bonded carbon atoms
When any atom other than hydrogen is attached, they are substituents or functional groups
Simplest organic compound; backbone
Free rotation
Lack saturation; least reactive
Nonpolar (hydrophobic & insoluble in water)
Boiling point increases with increasing molecular weight
Alkenes contain
Double bonds
Less flexible
More reactive
Hydrogenation, Halogenation, Hydrohalogenation, Hydration
Alkynes contain
Triple bonds
Not common
Hydrocarbons missing hydrogen are called
Alkyls (2 L’s)
Symbolized as “R”
The higher the octane,
The more predictable
Stereoisomers are a
Pair of molecules that have the same formula but the functional groups are in difference orientations
Isomers can only exist when
There is a restricted rotation of the molecule
Hydrogenation is the breaking of the
Double bonds & the addition of the hydrogen atom using the presence of a catalyst
Hydrogenated fats have a
Higher melting point & are solids at room temperature
More double bonds makes butter
Softer
Trans double bonds are
More stable that CIS, so the double bond introduced into the chain are largely trans
Aromatic compounds have a
Functional group called the benzene ring
Stable & common
The double bond in a benzene ring will
Exhibit resonance (hybrid)
A single, double, or triple bond is the
Sharing of electrons
What is Delocalized electrons?
Electrons freely moving around six carbons
More of a stable molecule
Less reactive
