A nonmetallic element is converted into a compound 'X' after a series of reactions. A little amount of 'X' when tested with blue litmus turns to red. 'X' on complete reaction with another compound 'Y' gave the product which did not respond to litmus test. Identify the correct sequence of the reactions.
