question 3 (1 point)
structural isomers are compounds that have ______ empirical molecular formul

Explanation:

Step1: Calculate degree of unsaturation

The formula for degree of unsaturation \(DU=\frac{2C + 2 - H}{2}\), where \(C\) is the number of carbon atoms and \(H\) is the number of hydrogen atoms.
For \(C_4H_6\):
\(DU=\frac{2\times4 + 2-6}{2}=\frac{8 + 2-6}{2}=\frac{4}{2} = 2\)
For \(C_4H_8\):
\(DU=\frac{2\times4+2 - 8}{2}=\frac{8 + 2-8}{2}=1\)
For \(C_4H_{10}\):
\(DU=\frac{2\times4+2-10}{2}=\frac{8 + 2 - 10}{2}=0\)
For \(C_6H_6\):
\(DU=\frac{2\times6+2 - 6}{2}=\frac{12 + 2-6}{2}=4\)

Step2: Relate degree of unsaturation to bonds

A triple bond has a degree of unsaturation of \(2\). A double bond has a degree of unsaturation of \(1\), and a ring also has a degree of unsaturation of \(1\).

Answer:

A. \(C_4H_6\)
