How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth?

You got half your answer inside your question. :-)

Most hypotheses about the origin of life on earth state that it arose from inanimate matter. Now, the nucleobases that make up RNA can be built out of the containments of the primordial soup.

the key step to life is a molecule that can rebuild itself. and as we know, RNA-polymerase consists mostly of RNA. these fact indicated that a world must've existed once, where the role of proteins was also taken bei RNA molecules. but this set aside, the essential part is that RNA can be built from ingredients of the primordial soup, and that RNA is the key molecule on the way from inanimate matter to life.

can anyone answer this question please.
in the following compounds; sodium chloride,hexane, ethanol, hydrochloric acids, sodium hydroxide, detergents and ammonium nitrates
you need talk about all of there 
-melting/boiling point
-solubility in water
with references to ionic or covalent 
-hydrophilic or hydrophobic 
-intramolecular forces

i dont think any one would be able to do it 
i challenge you guys to do it
