Chemistry - Halogen Derivative Question with Solution | TestHub

Electrophile accepts a pair of electrons. Al atom in$\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$has hextet; S atom in$\mathrm{S}{\mathrm{O}}_3$is positively charged, due to more electronegativity of O atom than S,$\mathrm{C}{\mathrm{l}}^{+}$ion is positively charged. Hence, these species accept a pair of electron.
