Question

COMPARE AND CONTRAST
PROPANE AND HEXANE

Answer 1

Propane and hexane are both unbranched alkanes; propane has three carbons, hexane has six carbons. So the shapes of the molecules are quite similar, the difference being that hexane is longer than propane.

If you're just comparing the two molecules themselves, that's all you can really say about them without a nit picking discussion of actual conformations. If you're comparing their properties, well, the problem you posted didn't say anything about comparing those.

Answer 2

similarities
both are alkane group
are saturated
they linked single bond only
have formula CnH2n+2
exhibit only structural isomerism.....
d/ce
propane has 3carbon and 8 hydrogen, hexane has 6 carbon and14 hydrogen...

Answer 3

sorry can you guys compare their properties and functions
as well

Answer 4

The properties are based on the physical differences between the two molecules and the consequences those differences have in terms of the interactions between multiple molecules.

They can't bond to each other but they can still interact. Transient deformations in the electron clouds around each molecule result in partial charges accumulating on different parts of each molecule. These partial charges are called dipoles and dipoles - partial negative and positive charges in different molecules - attract.

Basically, the molecules with more surface area - in this case hexane, because it has six carbons instead of three - can form more intermolecular interactions with each other than the smaller molecules. More intermolecular forces means the molecules attract each other more; you need to put more energy into the system to disrupt those interactions so a solution of hexane will have a higher boiling point than a solution of propane.

If you're talking about physical properties intrinsic to the molecules themselves, hexane has more CH bonds to break; therefore, burning one mole of hexane would release more energy than burning one mole of propane.
