Question

How many acyclic structural isomers of $C_4{H}_{7}Cl$ is possible?

• A. 10
• B. 5
• C. 6
• D. 8

Answer 1

The correct option is D 8

For a compound with molecular formula $C_c{H}_h{X}_x{N}_n{O}_o$
$\text{Degree of unsaturation}=(c+1)-\frac{h}{2}-\frac{x}{2}+\frac{n}{2}$
Where, X = Halogen
c=number of carbon atom
h=number of hydrogen atom
n=number of nitrogen atom
o=number of oxygen atom
In $C_4{H}_{7}Cl$
$\text{Degree of unsaturation}=(4+1)-\frac{7}{2}-\frac{1}{2}=1$
There are 6 possible acyclic structural isomer of $C_4{H}_{7}Cl$
