Explanation:
international union of pure and applied chemistry (full form)
it is the system of chemical symbols and formulae
Answer:
The IUPAC name of (CH3)3 C CH2 C (CH3)3 is 2, 2, 4, 4-tetramethylpentane
Explanation:
To write the IUPAC name of a compound we have to keep in mind :-
name of substituent with their position + word root for longest chain + primary suffix
Step 1:-
- Count the number of carbons to detect the longest chain.
- Also keep in mind, that the chosen chain has the greatest number of substituents and functional groups.
So as we count the number of atoms in (CH3)3 C CH2 C (CH3)3 we find that the longest chain has 5 carbon atoms and 4 substitutes.
=>Word root for longest chain is pent (as it has 5 carbon atoms in the longest chain)
Step 2 :-
See if the compound has any double or triple bond
- if it has double bound then primary suffix is ene
- triple bond then primary suffix is yne
- if no triple or double bond then primary suffix is ane
=> Since, the compound has no double or triple bond (case 3.) it will be named Pentane
Step 3 :-
find the substituents
here the substituents are CH3
( a substituent is an atom or group of atoms which replaces one or more hydrogen atoms on the parent chain of a hydrocarbon)
−CH3 methyl group or methanyl
=> position of methanyl is at 4 different places 2, 2, 4, and 4
=> Since, there are 4 same substitutes at 4 different places we'll add a prefix "tetra" in front of the substitute name
And we know that ,
name of substituent with their position + word root for longest chain + primary suffix
So, we write :-
2, 2, 4, 4-tetramethylpentane
[=> a hyphen ' - ' is placed in between a letter and a number
=> 2 numbers are separated by a comma]
