Why KBrF4 has a high melting point?

Answer 1

KBrF4 has a high melting point due to its ionic nature and the strong electrostatic forces of attraction between the positively charged potassium ions (K+) and the negatively charged bromine fluoride ions (BrF4-). This strong ionic bonding requires a significant amount of energy to break, resulting in a higher melting point compared to covalent compounds. Additionally, the molecular structure of KBrF4, which involves a tetrahedral arrangement of fluorine atoms around a central bromine atom, contributes to the stability and strength of the crystal lattice, further increasing the melting point.
