octane
C8h18
C8H18 or C2n Hn
The chemical formula of octane is C8H18.
C8H18 (octane) is expected to have the largest dispersion forces among these molecules due to its larger number of electrons and greater molecular weight, leading to stronger London dispersion forces.
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
When molecular compounds bond, they share electrons.
C8H18 bcz volatility depends upon intermolecular forces and alkanes have van der wall f.o.a and this force depends upon molar mass..Since c8h18 has lower molar mass so the force is less and intermolecular attraction is less.. So it can easily get vaporized . Therefore c8h18 is more volatile..
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
No, octane is not an ionic compound. Octane is a hydrocarbon, specifically an alkane, which consists of carbon and hydrogen atoms bonded together through covalent bonds. Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal.
Yes, molecular compounds can be formed from semimetals. These compounds result from the bonding of semimetal atoms to form molecules, often through sharing electrons in covalent bonds. Examples of molecular compounds with semimetals include carbon monoxide (CO) and boron trifluoride (BF3).
I don't know the exact formula but, i know the density of iso-octane: 0.69 g/ml And one gallon is equal to 3,840 ml so.... all you need is the volume.
Atoms are arranged in molecular compounds in groups.
