Arrange the following molecules according to the strength of their dispersion forces. Organize in order from largest to smallest
ki77a [65]

Explanation:

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

Therefore, more is the surface area occupied by the carbon chain more will be the dispersion forces present in it. Hence, less is the surface area occupied by a molecule less will be the dispersion forces present in it.  

Hence, the given molecules are organized from largest to smallest dispersion forces as follows.

CH_{3}CH(CH_{3})C(CH_{3})_{2}CH_{2}CH_{3} > CH_{3}CH_{2}(CH_{2})_{4}CH_{2}CH_{3} > CH_{3}CH_{2}CH_{2}CH_{2}CH_{3} > CH_{3}C(CH_{3})2CH_{3} > CH_{3}CH_{2}CH_{3} > CH4

In models of molecules, spheres of different colors and
AlladinOne [14]

Answer:

D

Explanation:

According to this question, each model of molecules in the options contains spheres of different colors and sizes representing different types of atoms. The atoms of the same element are the spheres of same color and size while atoms of different element are of different color or size.

Therefore, the model showing a molecule of a substance that is made up of three elements is model D because it is made up of three distinct spheres representing atoms of each element.

- The red sphere is the atom of the first element

- The big dark sphere is the atom of the second element

- The small white sphere is the atom of the third element
