(a)
Interpretation:
The type of interactive forces occurs between nitrogen molecules have to be identified.
Concept Introduction:
The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:
- Hydrogen bonding.
- London dispersion force.
- Ion – dipole force.
- Dipole – Dipole force.
(b)
Interpretation:
The type of interactive forces occurs between carbon dioxide and water molecules have to be identified.
Concept Introduction:
Refer to part (a).
(b)
Interpretation:
The type of interactive forces occurs between methanol and ammonia molecules have to be identified.
Concept Introduction:
Refer to part (a).

Identify the intermolecular forces which can operate between molecules of the following pure compounds: (b) N. (c) Numbering N. (d) 5. For the compounds in the previous question, what intermolecular forces would operate between the compound and water?arrow_forwardWhat types of intermolecular forces are present in each compound: (a) HCl; (b) C 2H 6 (ethane); (c) NH 3?arrow_forward
- Give typed explanation Draw Particle Level Diagrams for the Following Mixtures Displaying Intermolecular Forces: CH3NH2 & SO2, NH3 & CH3CH2OH, KNO3 & H2Oarrow_forwardQ2.2a - Identify the type of atomic bonds and intermolecular attractions present in each of the following scenarios: A compound made of positively-charged magnesium and negatively-charged sulfide atoms. The balanced bonds holding together the carbons and hydrogens in a molecule of Ethane. Hydrogen Fluoride is added to an aqueous solution. It dissolves due to interactions between partially-charged atoms in the Hydrogen Fluoride and Water molecules. The fatty acid tails on phospholipids are strongly attracted to each other because they are strongly repelled by water. This allows them to form phospholipid bi-layer structures. Ethanol contains an alcohol group with an oxygen atom that is strongly electronegative. This causes the molecule's electrons to be unbalanced, resulting in a partially-charged molecule.
