• # question_answer Which of the following will not occur [MP PET/PMT 1988] A) $Fe+{{H}_{2}}S{{O}_{4}}\to FeS{{O}_{4}}+{{H}_{2}}$ B) $Cu+2AgN{{O}_{3}}\to Cu{{(N{{O}_{3}})}_{2}}+2Ag$ C) $2KBr+{{I}_{2}}\to 2KI+B{{r}_{2}}$ D) $CuO+{{H}_{2}}\to Cu+{{H}_{2}}O$

Electronegativity of ${{I}_{2}}$ is less than $B{{r}_{2}}$. Therefore unable to displace bromine.
