Complex alternative question with OR, do I need the verb before the subject twice?

Which is correct?

Would you like to have such feature or it is unnecessary?

or

Would you like to have such feature or is it unnecessary?


Solution 1:

Well, in terms of grammar, the second sentence would be correct, because it contains two questions that can be appropriately punctuated with a single question mark at the end.

The first sentence, however, contains both a question and a declarative sentence ("it is unnecessary"). The question mark would then be appropriate only for the question.
