name it's iupac name​

Answer 1

Explanation:

ethan1one. or simply ethanone

Answer 2

Answer:

Ethan-1-al

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 the given compound we find that the longest chain has 4 carbon atoms and 1 functional groups.

=>Word root for longest chain is eth (as it has 2 carbon atoms in the longest chain)  

Step 2 :-  

See if the compound has any double or triple bond  

1. if it has double bound then primary suffix is ene  

2. triple bond then primary suffix is yne  

3. 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 Ethane.

Step 3 :-  

find the substituents / functional groups

here, there are no substituents.

( a substituent is an atom or group of atoms which replaces one or more hydrogen atoms on the parent chain of a hydrocarbon)

functional group is (HC=O) which is an aldehyde group

=> for aldehyde group suffix "-al" is added

 

And we know that ,  

name of substituent with their position + word root for longest chain + primary suffix  

So, we write :-  

Ethan-1-al

[=> a hyphen ' - ' is placed in between a letter and a number  

=> 2 numbers are separated by a comma]
