Intermolecular bonding Quiz 2

chemistry

 If the distance between the molecules is large then intermolecular forces will be

 Intermolecular forces are those which are present in between the atoms of different molecules  and intramolecular forces are attractive forces within the moleucles.

 Intermolecular forces are those forces that define the interaction between the molecules; these are forces of attraction or repulsion which act between the atoms and other types of neighbouring particles which can be atoms or ions. If the molecules have a large internuclear distance then the forces are also weak in nature as attraction and repulsion are very low in this case. 

 Which of the following has the highest melting point?

   Intermolecular forces are those which are present in between the molecules. MOre the molecular weight of the molecule  more will be the intermolecular forces and hence higher is the melting point.

 Melting point is that point where solid starts changing into a liquid state so they need to move freely as in liquid state the molecules have greater internuclear forces between them. So we know that fluorine is more electronegative as compared to another, so it has greater forces of attraction so it needs high temperature to get converted in any other state.

 Ion-Dipole interactions are those interactions that occur between the ion and polar molecules. The main example of Ion-Dipole interaction is sodium chloride mixed in water.

 Ion-Dipole interactions are similar to dipole-dipole interactions. The only difference is it can act between ions and polar molecules. Whereas dipole-dipole interaction takes place between only polar molecules. The strength of the polar molecule depends on the dipole moment where the dipole moment measures the polarity of the chemical bonds and it also depends on the size of the polar molecule and also on the size and charge of the ion as it gives us interaction between polar molecule and ion.

 Which of the following show hydrogen bonding ?

 Hydrogen bonding is described as a strong Dipole-Dipole interaction and in this bonding, the molecules which donate hydrogen atoms are known as donor molecules and the molecule containing lone pair is termed as acceptor molecules.

   Hydrogen bonding defines the attraction between the lone pair of an electronegative atom or a hydrogen atom which is bonded with an electronegative atom usually oxygen, nitrogen or fluorine are termed as electronegative in nature. Here, option A carries the electronegative atom oxygen along with hydrogen so in this case hydrogen bonding is present as compared to others.

 Which intermolecular forces are responsible for the fact that ice is less dense than liquid water?

 Intermolecular forces are those forces that attract the molecules together in the liquid state, intermolecular forces of attraction are weak in the liquid state as compared to solid that’s why liquids tend to flow while solid does not have.

Hydrogen bonding defines the attraction between the lone pair of an electronegative atom or a hydrogen atom which is bonded with an electronegative atom usually oxygen, nitrogen or fluorine are termed as electronegative in nature. Now, we know that ice has a lesser density as compared to water and does not produce hydrogen bonding like water.
