Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which don't have an -O-H or an -N-H group. That is why it is often used to identify an unknown substance in qualitative chemistry. Except in some rather unusual cases, the hydrogen atom has to be attached directly to the very electronegative element for hydrogen bonding to occur. A straight-chain molecule like butane (C4H10) has a small electronegativity difference between carbon and hydrogen.
