They have a complete electronic configuration .their P shell is p6 therefore cannot gain or loose electron.
Answer:
b) 1.3 E2 mL
Explanation:
∴ m = 90.0 g
∴ density = 0.70 g/mL
⇒ V = m / d
⇒ V = 90.0g / 0.70 g/mL
⇒ V = 128.571 mL
⇒ V = 1.285 E2 mL ≅ 1,3 E2 mL
Answer:
Attraction between molecules of methane in liquid state is primarily due to "London dispersion force".
Explanation:
Methane is a non-polar and aprotic molecule. Hence there is no dipole moment in methane as well as no chance of hydrogen bonding formation by methane.
We know that all molecules contain electrons. Therefore transient dipole arises in every molecule due to revolution of electrons around nucleus in a non-circular orbit. Hence an weak intermolecular attraction force is always present in every molecule as a result of this which is termed as "London dispersion force".
So, attraction between molecules of methane in liquid state is primarily due to "London dispersion force".
