Question

write their names ????source:: increasing oder of priority for some functional groups...chemistry​

Answer 1

Answer:

Let’s say you’re trying to name a molecule. You’re familiar with the familiar naming suffixes like -ol, -ene, -ane, -oic acid and so on. But then you come across a molecule which has multiple functional groups.

What do you do? What suffix do you give the molecule?

We need some kind of priority system for nomenclature. And so, IUPAC (think of the “Ministry of Magic”, but for chemists) has developed one. If you have a molecule with, say, a carboxylic acid and a ketone you consult the table. The functional group with the highest priority will be the one which gives its suffix to the name of the molecule. So in example #1 above, the suffix of the molecule will be “-oic acid”
