There are four type of intermolecular forces: ionic, dipole-dipole, hydrogen bonds and London disperssion forces.
CH4 have no ions, so there are not ionic forces.
CH4 is a symetrical molecule, so there cannot be a net dipole in the molecule, so there is not dipole-dipole interaction.
Hydrogen bonding is only possbile when H is bonded to N, O or F, beacuse they are the atoms that considerable higher electgronegativy than hydrogen.
So, the only intermolecular force present in CH4 molecules is London disperssion forces, which is a force present in any molecule and is the weakiest one. That explains the low melting and boiling points of CH4.

Answer:
<h2>69.3 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
volume = 55 mL
density = 1.26 g/mL
mass = 1.26 × 55 = 69.3 g
We have the final answer as
<h3>69.3 g</h3>

according to the law of circumference and the perpendicular area of a circle the answer would be c
Explanation:
Explanation:
More is the mass of directly attached atom more will be the priority of the group attached to the alkyl or aryl chain.
Atomic mass of oxygen is 16, nitrogen is 14, carbon is 12, and hydrogen is 1.
This means that as the atomic mass of oxygen is greater than rest of the given atoms. So, priority will be given to the oxygen atom.
Thus, we can conclude that the given groups are placed in order of decreasing priority as follows.
-OH > 
> -COOH > -H
