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.

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

Explain why the larger the hydrocarbon molecule is the more

RideAnS [48]

Answer:

Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable

If the mole fraction of nitric acid (HNO3) in an aqueous solution is 0.275, what is the percent by mass of HNO3?

jeka94

Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.
