giúp em câu a b c d với ạ, em cảm ơn nhìuuuuu

Đáp án:

\(CH_3^{} - CH(OH) - C_6^{}H_5^{}\)

\(b)C_6^{}H_6^{} + HNO_3^{}\xrightarrow{{H_2^{}SO_{4_d^{}}^{}}}C_6^{}H_3^{}(NO_2^{})_3^{} + H_2^{}O\)

\(c)CH_2^{} = CH - C_6^{}H_5^{} + H_2^{}O \to CH_3^{} - CH(OH) - C_6^{}H_5^{}\)

\(d)CH_2^{} = CH - C_6^{}H_5^{} + HB{\text{r}} \to CH_3^{} - CH(B{\text{r}}) - C_6^{}H_5^{}\)
