To make chloro, bromo or cyano benzene from aniline, you first form benzene diazonium salt with NaNO₂ and HCl, then use CuCl for chloro, CuBr for bromo, or CuCN for cyano—all in our NCERT, baba. But memorizing these for boards feels as tangled as our lane’s water tap issues, where real chemistry isn’t just reactions. Over mishti cha with Baba, I think fixing our para’s taps needs more than a textbook catalyst.
