what should you see when 2-butanol is treated with NaI-I2?

if you pour ethylene glycol into water it mixes in all oroprtions. but if you bubble butane, a gas of comparable molar mass through water, it does not mix but just bubbles away. how do you explain these differences?

    Ethylene glycol is more polar because it has two OH groups AND it is shorter hydrocarbon chain. Butanol is a longer chain and it is less polar.
