Is Hbr an ionic compound?

Hydrogen bromide is covalent. Pure HBr has a melting point of -114.20C and a boiling point of -85.10C. The molecule has a dipole moment which is due to the poalr nature of the chemical bond. In water HBr is a strong acid, hydrobromic acid, and is pretty well completely dissocaiated.

Why boiling point of HBr is higher than HCl?

HBr and HCl are both polar have similar dipole-dipople forces. This can be determined by looking at their electronegativities. Now, you need to determine their London Dispersion Forces- HBr is bigger than HCl (it is lower on the periodic table), so it has much more dispersion force.


Which has a higher Boiling point of HBr or HF or HCl?

Is a chemical composition and chemical properties the same thing?

No. Chemical composition is "What is this substance made of". Chemical Properties are "How does this substance react when I do XYZ to it". Examples of Composition are Cl_2, HBr, CH_4, C_2H_6 Examples of Properties are Boiling Point, Melting Point, Electronegativity, Reactivity, Valence Electrons.
