out of all hydrides of chalcogens H2S has lowest boiling point due to absence of hydrogen bonding and gaseous nature( having weak intermolecular forces).
Hydrogen Sulphide has lowest boiling point because it has very low intermolecular attraction forces.
Hydrogen sulfide does not have hydrogen bonding since sulfur has a low electronegativity. This reduces the boiling point of hydrogen sulfide since it is easier to break the intermolecular forces between molecules of hydrogen sulfide.
