Question

Which best describes the melting point difference between salt and sugar?(1 point)

A). The ionic bonds in salt result in a higher melting point than the covalent bonds in sugar.
B). The covalent bonds in salt result in a higher melting point than the ionic bonds in sugar.
C). The ionic bonds in salt result in a lower melting point than the covalent bonds in sugar.
D). The covalent bonds in salt result in a lower melting point than the ionic bonds in sugar.

Answer 1

A). The ionic bonds in salt result in a higher melting point than the covalent bonds in sugar.

Ionic lattice forces in salt (strong electrostatic attraction between ions) require much more energy to break than the intermolecular forces between sugar molecules, so salt melts at a much higher temperature.
