im not able to understand the steps involved in the IUPAC nomenclature for branched chain saturated hydrocarbons......in addition to this im not getting that how does 2-methylpropane differ from isobutane coz both of them have same structues?Can i write isobutane instead of methyl propane?What difference would it make?
- Identify each of the branches (side-chains).
- Use the lowest number combinations for the branches (side-chains).
- Name each branch or side-chain (alkyl group) :
methyl CH3 ethyl C2H5 propyl C3H7
- For more than 1 of the same alkyl group use:
di = 2 tri = 3 tetra = 4
- Use commas between numbers, eg, 1,2 or 2,3
- Use hyphens between numbers and words, eg, 2-methyl or 2,3-dimethyl
- If there is more than 1 type of branch or side-chain, arrange their names alphabetically,
ie, ethyl groups are named before methyl groups which are named before propyl groups
