Which of the following is correct?
Hi, Shivam Raj,
That word is not in any dictionary that I know of, though I don't want to discourage you from using it. Prefixes can often be added to verbs.
Both ways of spelling the word are correct, and there is another option as well. You could use a diaeresis above the o: deöperationalize.
