Isopropanol precipitates the RNA. Up to that point it's generally in solution. Centrifuging the tube after this step should leave a very faint but generally visible white smudge/pellet of RNA. The ethanol steps that follow the isopropanol precipitation are simple washes.
It inactivate the RNase and prevent RNA to denature.
It catalyzes the bonding of RNA nucleotides.
i was asking you
trizol helps in maintaining the integrity of the RNA and keeps it intact since RNA is very unstable due to the presence of hydroxyl groups which gives it a free radical.
. What are RNA and DNA?
It act as a buffer in Northern blotting.

Large molecules of RNA gets aggregates with the LiCl2 approx 3M solution and helps in proper precipitation. remember let the mixture hold overnight in 4c.

The role of NaCl or sodium chloride in RNA isolation is part of the denaturing process. It is often called the wash step.
Break open the cells, stabilize RNA, inhibit RNAse.
Most often, RNA is removed using the enzyme RNAase
it solubilize the lipids and protein and remove them.
for phase separation
it helps in precipition step...

RNA manufactures protein
