Question

2. What kind of intermolecular bond exists between molecules of CH4? 3. Write the equation for the reaction showing the first electron affinity step in the formation of ferrous bromide, with states 4. What is the volume of the atom of an element that crystallizes as a body-centered cube if the volume of the unit cells 197x 102cm? 5. What is the mass of 2.54 ml of H2 at 195 "C and 850 mmHg? 6. It takes 59 seconds for .50L of nitrogen gas to effuse through an apparatus. How many seconds for the same volume of 2 liters of hydrogen gas to effuse through the same apparatus?

Explanation / Answer

Ans 2 :

CH4 is the chemical formula of methane. It is the simplest alkane hydrocarbon that has only single carbon.

Since the electronegativities of C and H are very close , the bonds are non polar. So the only intermolecular bonds existing in between these molecules are : London dispersion forces.

These forces are very weak in nature.
