Answer:
(a) CH₃CH₂CH₂CH₂CH₂OH
(b) CH₃OH
(c) CH₃CH₂CH₂CH₂CH₂OH
Explanation:
In alcohols, the -OH group is responsible for the polarity. The longer the non-polar hydrocarbon chain, the less polar is the compound.
Regarding solubility, we will consider the general rule "like dissolves like", meaning polar is soluble in polar and non-polar is soluble in non-polar.
(a) I₂ is non-polar, so it will be more soluble in the least polar solvent, which is pentanol (CH₃CH₂CH₂CH₂CH₂OH).
(b) NaCl is an ionic compound, that is, there is a big difference in electronegativity between the atoms. Then, it will be soluble in the most polar alcohol, methanol (CH₃OH).
(c) Pentane (CH₃CH₂CH₂CH₂CH₃) is non-polar, so it will be more soluble in the least polar solvent, which is pentanol (CH₃CH₂CH₂CH₂CH₂OH).

Explanation:
We define the rate of reaction as the rate of disappearance of reactants or the rate of appearance of products. The negative sign written before the rate of change of concentration of reactants shows that their concentration decreases with time.
The rate of reaction in terms of the concentration of each reactant or product is shown below;
Rate = -1/4d[NH3]/dt
Rate = -1/5d[O2]/dt
Rate = 1/4d[NO]/dt
Rate = 1/6[H2O]/dt
It is known as the Magnetic Field.
