Question

what is the order of melting point among hydrogen halides(HF,HCL,HBR,HI)

Answer 1

Answer:

the order of melting points among hydrogen halides is

HI > HF > HBR >HCL

Explanation:

HF has more melting point than expected due to intermolecular hydrogen bonding

Answer 2

Answer:

Order of melting point of hydrogen halides are

HI > HF > HBr > HCl

Explanation:

Order of melting point of hydrogen halides are HI >HF > HBr > HCl

Here melting point of hydrogen fluoride is greater than hydrogen chloride and hydrogen bromide because fluorine has high electronegativity than other halogens. Therefore it undergoes hydrogen bonding. So the intermolecular force between the molecules increases and it leads to a higher melting point of hydrogen fluoride.
