HI / Red P is one of d strongest reducing agents..... so it reduces all the functional groups to yield alkanes.... yes in the above case it yields n-hexane...

Alkanes are formed when alcohols, aldehydes, ketones or fatty acids are reduced with hot hydroiodic acid (aqueous solution of HI) and red phosphorus at 150-200*c
