Explanation:
Element which gives golden flame on heating is sodium. Therefore, A is sodium.
Element whose atomic number is 17, is chlorine. Therefore, B is chlorine.
When element A and B reacts with each other then the reaction will be as follows.
Hence, from the reaction we can see that compound C is NaCl (sodium chloride).
Now, chemical equation for electrolysis of aqueous solution of compound C is as follows.
Thus, compound D is NaOH (sodium hydroxide).
