There are no interrogative pronouns, only interrogative verbs, and verbs are generally by default the first element in a sentence. Aside from (possibly) the negative particle, in content interrogative sentences, nothing comes before the verb. In standard indicative sentences it is acceptable to place a small set of common adverbs before the verb (instead of at the end of the sentence), but this is not so when the verb is a content interrogative.
