Question

Give the IUPAC name of following compounds:
CHF2C Br.cIf:​

Answer 1

Answer:

There are two carbons, so the root of the name will be '-ethane'

We need to number the carbon atoms

1

or

2

, so I'll choose the carbon bonded to Br, Cl and F to be the first carbon, since it has the most non-hydrogen substituents on it.

Therefore, there is one chlorine on the 1-carbon, one bromine on the 1-carbon, and one fluorine on the 1-carbon. There are also two fluorines on the 2-carbon, so we have:

1-chloro

1-bromo

1,2,2-trifluoro

and,

ethane

We list the prefixes in the IUPAC name in alphabetical order, so in full it is

1-bromo-1-chloro-1,2,2-trifluoroeth9ane.

hope it helps you
