drag each tile to the correct box. arrange the molecules in order from strongest intermolecular force to…

Explanation:

Step1: Understand intermolecular force principle

Larger - sized non - polar molecules have stronger London dispersion forces. The more electrons a molecule has, the stronger the London dispersion force.

Step2: Compare the number of electrons in each molecule

The number of electrons in a molecule is related to the sum of the atomic numbers of its atoms. For $CH_4$ (1 carbon and 4 hydrogens), the total number of electrons is $6 + 4\times1=10$. For $C_2H_6$ (2 carbons and 6 hydrogens), it is $2\times6+6\times1 = 18$. For $C_3H_8$ (3 carbons and 8 hydrogens), it is $3\times6 + 8\times1=26$. For $C_4H_{10}$ (4 carbons and 10 hydrogens), it is $4\times6+10\times1 = 34$.

Step3: Arrange according to electron - number

Since $C_4H_{10}$ has the most electrons, it has the strongest intermolecular force, followed by $C_3H_8$, then $C_2H_6$, and $CH_4$ has the weakest.

Answer:

$C_4H_{10}$, $C_3H_8$, $C_2H_6$, $CH_4$
