How can I know the IUPAC names of complicated compounds?
Plz give at least 5 examples and explain whole thing properly

Hey Friend,
Here are the rules of Nomenclature by IUPAC System -
Every Name must consist of -
1. Root Word - Number of carbon atoms in chain
⇒ 1C ---> Meth-
⇒ 2C's ---> Eth-
⇒ 3C's ---> Prop-
⇒ 4C's ---> But-
2. Primary Suffix - Nature of carbon chain
⇒ single bond ---> -ane
⇒ double bond ---> -ene
⇒ triple bond ---> -yne
3. Secondary Suffix - Particular functional group
⇒ -OH ---> -ol
⇒ -CHO ---> -al
⇒ -COOH ---> -oic acid
4. Prefix - additional substituent alkyl or functional group.
⇒ di-tri-tetra
⇒ bromo-chloro
⇒ ethyl-methyl
Naming an Organic Compound -
1. The longest continuous chain of 'C' atoms is selected.
2. Numbering the Carbon atoms...
(i) Alkyl group gets the smallest number (if present)
(ii) Functional groups gets the smallest number (if present)
(iii) Functional groups are arranged alphabetically.
(iv) Smaller Alkyl group gets smaller number.

Hope it helps!

In particular, IUPAC is directly involved in the following:
establishing thecriteria for a new element discoverydefining the structure of a temporary name and symbolassessing claims resulting in thevalidation and assignation of an element discoverycoordinating thenaming of a new element, involving the research laboratory and allowing for public commentssetting up precise rules for how to name a new elementdefining Group 1-18 and collective namesdetermining which elements belong toGroup 3regularly reviewingstandard atomic weights
The table is yours to use. Details about thelatest release are provided above. Details below provide multiple references to IUPAC journal in Pure and Applied Chemistry (PAC) and magazine Chemistry International (CI).
