The number of isomers for the compound with moelecular formula `C_(2)BrCIFI` is

Options

A. `5`
B. `4`
C. `6`
D. `3`

Answer

C

Explanation

First calculate the degree of unsaturation or double bond equivalents `(DBEs)`:
`DBE = (sumn(v-2))/(2) +`
`=(2(4-2)+1(1-2)+1(1-2)+1(1-2)+1(1-2))/(2)+1`
`= (0)/(2)+1=1`
This implies the presence of one `C = C` or a cyclic structure, but on cyclie structure is possible as there are just two carbon atoms.
