Nomenclature Part 1 Flashcards
Defi
same molecular formula
Isomers
different CONNECTIVITY of atoms
CONSTITUTIONAL
different FUNCTIONAL groups
Functional
different POSITIONS of functional group
Positional
different CARBON skeleton
Skeletal
same CONNECTIVITY but different SPATIAL ORIENTATION of atoms
Stereoisomers
different, non-interconverting spatial arrangement of atoms; not the result of rotation about single bonds; different compounds
Configurational
different, interconverting spatial arrangement of atoms; result of rotation about single bonds; same compound
Conformational
Result from RESTRICTED ROTATION around double bond or on cyclic alkanes
Geometric
Around a CHIRAL carbon
Optical
nonsuperimposable mirror images
Enantiomers
nonmirror images
Diastereomers
Usually uses the name given when it was discovered
Common
Names compounds as DERIVATIVE of a parent compound
Derived
IUPAC acronym
International Union of Pure and Applied Chemistry
it is the most systematic naming and it is based on the LONGEST CONTINUOUS CHAIN of
C atoms
IUPAC
position/s, number, & name/s of substituents; number of C of
parent functional group
Prefixes
position and name of functional group
Suffix
Where and what are the substituent
Prefix
How many carbons?
Parent
Where is the primary functional group?
Locant
What is the primary functional group?
Suffix
Contains carbon and hydrogen only
Hydrocarbons
Open chain (acyclic)
Aliphatic
Straight and Branched
Aliphatic
Has a closed ring but no aromaticity
Alicyclic
Has a benzene ring
Aromatic
Contains C-C bonds
Saturated
Contain at least one C=C or C to C triple bond
Unsaturated fats are
General Formula of Alkane
CnH2n+2
General formula of Alkene
CnH2n
General Formula of Alkyne
CnH2n-2
what is the alkanes also known as?
paraffins
meaning is “slight affinity”
L. parum affinis
react under appropriate conditions with oxygen, chlorine, and a few other substances
Properties of Alkanes
Found in WAXY COATING in CABBAGE LEAVES
nonacosane (C29H60)
Found in wood oil of the JEFFREY PINE common to the Sierra Nevada Mountains of California
Heptane (C7H16)
most commons sources of alkanes:
natural gas and petroleum deposits
consists chiefly of METHANE but also contains ethane, propane, and butane
Natural Gas
A complex mixture of hydrocarbons that must be first separated in various fractions and then further refined before it can be used/
Petroleum
Occurs when irradiated with ultraviolet light
Reaction with chlorines of alkanes
Line-angle formula
Skeletal structure
The same molecular formula but different structural formula
Alkanes: Constitutional Isomers
unbranched chains
n (normal)
methyl group attached to the 2nd C
Iso
4 methyl groups attached to one C
Neo
oblique view of C-C bonds
Sawhorse
along a C-C bond
Newman Projection
Two types of represenations of aliphatic alkanes
Sawhorse
Newman Projection
C-H bonds are as far awat from each other; more stable
Staggered
C-H bonds are as close as possible; less stable
Eclipsed
Contains two fewer hydrogen atoms than an aliphatic alkane wth same number of carbon atoms
Alicyclic alkane
Alkyl group + Halogen
Alkyl halides
released in large amounts by ocean kelp, forest fires, and volcanoes
Chloromethane
industrial applications of alkyl halides
solvents
inhaled anesthetics
refrigerants
pesticides
Trichloroethylene
solvent
Halothane
inhaled anesthetics
Dichlorodifluoromethane
refrigerant
bromomethane
fumigant
What is alkenes also known as?
Olefins
Plant hormone that induces ripening in fruit
Ethylene
Major component of turpentine
α-pinene
a polyalkene that contains 11 double bonds; the orange pigment responsible for the color of carrots; and a valuable dietary source of vitamin
β-carotene
separated by atleast 2 single bonds
isolated
adjacent
cumulative
alternating with single bonds
conjugated
