Hydrogen bond is formed between the hydrogen and an atom with high electronegativity surrounding the hydrogen. The hydrogen bond can be intermolecular or intramolecular depending if it is formed in between two molecules or within a molecule respectively. Solution of ethanol in water shows negative deviation.
