Among the following, which have highest melting point?

Options

Alonic solids
BPseudo solids
CMolecular solids
DAmorphous solids

Correct answer

A. lonic solids

Step-by-step solution

Ionic solids are formed by three dimensional arrangements of positive charged ions i.e. cations and negative charged ions i.e. anions. These ions are held together by coulombic(electrostatic) forces and hence, ionic solids are hard and brittle. Ionic solids have highest melting point due to strong electrostatic force of attraction.
