Do Propanol, Butanl,Pentane,Hexane and Ethanol have hydrogen Bonding?

In order for H-bonding to occur you need a molecule containing an H atom attached to an atom with a very high electronegativity(attraction for bonded electrons) and small size: fluorine, nitrogen, or oxygen! The (-anol) = alcohols = OH group so you met the criteria and have H-bonding.

Pentane and hexane which do not have an oxygen show no hydrogen bounding
For butanl , you have missed a letter . If this letter is O you have hydrogen bounding
Propanol and ethanol have hydrogen bounding since they contain Oxygen

A hydrogen bond is a special type of attractive interaction that exists between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This type of bond always involves a hydrogen atom, thus the name. Hydrogen bonds can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly).[1] The typical hydrogen bond is stronger than van der Waals forces, but weaker than covalent or ionic bonds.
Hydrogen bonds can vary in strength from very weak (1-2 kJ molâ1) to extremely strong (40 kJ molâ1), as in the ion HF2â. Typical values include:
O—H...:N (29 kJ/mol)
O—H...:O (21 kJ/mol)
N—H...:N (13 kJ/mol)
N—H...:O (8 kJ/mol)

-ols do, -anes don't.
