16.0424 g/mol is the answer sir or ma’am
Answer: the correct option is (C).
Explanation:
Covalent compounds have lower melting and boiling points due to presence of weak inter-molecular forces by which molecules are weakly associated to each other. Hence, melting and boiling of covalent compounds occurs at low temperatures.
Usually, Covalents compounds have following properties:
- They are brittle solids
- They do not conduct electricity
- They do not have rigid crystal structure.
- They exist in all states: solids, liquids and gases.
mid-1700s during the Industrial Revolution
Explanation:
Vander waal forces are defined as the weak electric forces which tend to attract the neutral molecules towards each other in gases, liquefied and solidified gases. And, it is also present in all organic liquids and solids.
Vander wall forces are basically present in all type of molecules. More is the number of carbon atoms present in a molecule more will be the presence of Vander waal forces.
As a result, butanol will have strongest intermolecular force of attraction because it contains more number of carbon atoms and also it has more electronegative oxygen atom.
Whereas n-pentane will have the weakest intermolecular force of attraction between its atoms.
