a Consider the following two compounds, silane (SiH4) a gas and magnesium hydride (MgHz) a solid at room temperature. Using your knowledge of bonding and intermolecular forces give a detailed explanation of why these two compounds exist in different states at room temperature (25 °C) even though they are both similar sized (32.12 and 26.32 g/mol respectively) and both contain hydrogen.
