Which compound would have a stronger ionic bond?
Alf3
Why do some ionic compounds have low melting points?
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound (Figure 6.2. 1) .
Which bond has a high melting point?
ionic bonds
Can hydrogen bonds affect melting point?
Therefore, compounds containing hydrogen bonds require more energy to break the attraction between molecules than a nonpolar compound that only has London dispersion forces. Thus, the presence of hydrogen bonds increases the melting point of a compound.
What type of bonds have the highest melting point?
Short answer: Compounds with ionic bonding have higher melting points than those with covalent bonding.
Do all ionic bonds have high melting points?
Explanation. Ionic compounds are held together by electrostatic forces between the oppositely charged ions . As the ionic lattice contains such a large number of ions, a lot of energy is needed to overcome this ionic bonding so ionic compounds have high melting and boiling points.
Do hydrogen bonds have high boiling points?
Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which don’t have an an -O-H or an -N-H group. The hydrogen bonding makes the molecules “stickier,” such that more heat (energy) is required to separate them.
How does hydrogen bonding cause water to have a high melting point?
Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces. Water also has a high specific heat.
Why do hydrogen bonds affect boiling point?
Hydrogen bonding between molecules(inter mlecular) is one such attractive force. In water because of the hydrogen bonding attraction between molecules greater energy is needed to separate them from against their inter molecular attraction, therefore higher boiling point.
