Nomenclature of OC
IUPAC rules of naming OC
Saturated compounds (alkanes)
Unsaturated compounds (alkene alkyne)
Numbering done where double bond closer followed by triple bond and acc locant rule
Named as derivative of alkynes
General formula
Haloalkane
Alphabetical rule followed
Locant with greater no preferred
Functional compounds
Functional group should have lowest no
Can violate lowest sum rule
Polyfunctional compounds
More than one similar complex substituent
di, tri, tetra repalced by bis, tris, tetrakis
Polyfunctional compound containing more than two like fun group
Linked directly
doesnt include any of the group
3 Linked indirectly
two form part of parent chain while one is substituent
Naming of
Alicyclic compounds
Prefix : cyclo
More branched gets lower number
lowest sum rule
If hte side chain consists of fun group or double/triple bong then it is treated as substituent
No of substituent C _< No of C in ring then its is named cycloalkyl alkane
No of substituent C > No of C in ring then it is named alkyl cycloalkane
If more than one alicylic ring attached then it named cycloalkyl alkane
Multiple bong gets low no
Named derivative of benzene if directly atached
Bicyclo comp
Has two fused cycloalkanes
Prefix: Bicyclo
[Number of C atoms larger. Number of C atoms in small ring. Number of C atoms in bridge head]
Numbering started from bridge head
Tricyclo
Numbering started from bridge head
Numbering started from bridge head
Spiranes
Are polycyclics that share only 1 C atom
Numbering started next to fused a C atom in lower member ring
Cyclic ethers
(CH2)nO
Aromatic
Substituted benzene compounds
