Question

What physical property is identical for the isomers of `C_5H_12` and `C_6H_14`?

Answer 1

The molecular masses of each isomer is necessarily a constant .

Explanation:

`"Pentane"`, `C_5H_12`, can form THREE structural isomers: `"isopentane"`; `"n-pentane"`; and `"neopentane"`.

`"Butane"`, `C_4H_10`, can form TWO structural isomers: `"isobutane"`; `"n-butane"`.

For each isomeric series, while they have (slightly) different chemistries, and physical properties. THE MOLECULAR MASSES, `58.12*g*mol^-1`, and `72.15*g*mol^-1`, respectively, ARE A CONSTANT...
