Is corn starch polar or nonpolar?

Answer 1

Both polystyrene and cornstarch are made of polymers, which are long-chain molecules that have a basic repeating unit. Some polymers are polar (such as cornstarch), while others are non-polar (such as polystyrene). The polar parts of cornstarch are hydroxy (--OH) groups that hang off the main chain. These hydroxy groups interact with water molecules to form hydrogen bonds, and as a result, cornstarch is soluble in water.-Journal of Chemical Education

According to this, cornstarch is polar and the source seems pretty credible was the Google entry right under this one so way to look it up!
