• # question_answer Four reactions are given below (i)$2Li+2{{H}_{2}}O\to 2LiOH+{{H}_{2}}$ (ii)$2Na+2{{H}_{2}}O\to 2NaOH+{{H}_{2}}$ (iii)$2LiN{{O}_{3}}\xrightarrow{Heat}2LiN{{O}_{2}}+{{O}_{2}}$ (iv)$2NaN{{O}_{3}}\xrightarrow{Heat}2NaN{{O}_{2}}+{{O}_{2}}$ Which of the above, if any, is wrong A) (iv) B) (iii) C) (i) D) None of these

Lithium nitrate on heating gives $\underset{(S)}{\mathop{4LiN{{O}_{3}}}}\,\,\xrightarrow{\Delta }\,\underset{(S)}{\mathop{2L{{i}_{2}}O}}\,+4N{{O}_{2}}\uparrow +{{O}_{2}}\uparrow$
