Viết đồng phân thơm C8H10 và C7H7Cl

+ \(C_8H_8\)

Ta có:

\({k_{X}} = \frac{{8.2 + 2 - 10}}{2} = 4\)

CTCT:

\(C_6H_5-CH_2-CH_3\)

\(o-CH_3-C_6H_4-CH_3\)

\(m-CH_3-C_6H_4-CH_3\)

\(p-CH_3-C_6H_4-CH_3\)

+\(C_7H_7Cl\)

\( \to k_X=\frac{7.2+2-(7+1)}{1}=4\)

CTCT:

\(C_6H_5-CH_2-Cl\)

\(o-Cl-C_6H_4-CH_3\)

\(m-Cl-C_6H_4-CH_3\)

\(p-Cl-C_6H_4-CH_3\)
