2 answers:
are soluble in both water and hexane.
Further explanation:
The property of any substance (solute) that makes it able to dissolve in other solvents or substances is known as solubility. It depends on the physical and chemical properties of both solute and solvent. The solute is the component that is present in a smaller amount while the solvent is present in a larger amount. The solubility is generally determined by the principle of “like dissolves like”.
Hexane is a non-polar hydrocarbon consisting of six carbon atoms linked to each other in a straight chain. Water is a polar solvent due to the presence of a highly electronegative oxygen atom in it.
Alcohols have the general formula of ROH, where R represents the carbon chains or rings attached to the hydroxyl functional group. So alcohols have both polar as well as non-polar parts in them.
Smaller alcohols such as methanol, ethanol, and propanol are soluble in water due to their hydroxyl groups. These can form hydrogen bonds with water and becomes soluble in it. But larger alcohols have a large, non-polar part which is hydrophobic in nature. So larger alcohols like pentanol, hexanol, heptanol and octanol become insoluble in water. Due to the presence of large non-polar parts in higher members of alcohol, these are also soluble in hexane.
1-propanol is alcohol consisting of three carbon atoms while 1-pentanol has five carbon atoms. So 1-propanol is soluble in water but 1-pentanol is soluble in hexane only.
1-butanol is an alcohol having four carbon atoms whereas 1-pentanol has five carbon atoms. So 1-butanol is slightly soluble in water but 1-pentanol is soluble in hexane only.
Ethanol is the alcohol of two carbon atoms and 1-butanol has four carbon atoms. Ethanol is soluble in water but 1-butanol is slightly soluble in water.
Ethanol is the alcohol of two carbon atoms and 1-propanol has three carbon atoms. Both also contain a non-polar hydrophobic end in them so these are soluble in both water and hexane.
Methanol is the alcohol of one carbon atom while 1-butanol has four carbon atoms in it. Methanol is highly soluble in water but 1-butanol is only slightly soluble in water.

Answer : The correct option is, (e) precipitation reaction
Explanation :
Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Precipitation reaction : It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined.
The insoluble salt that settle down in the solution is known an precipitate.
Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.
It is represented as,
In this reaction, A is more reactive element and B is less reactive element.
Acid-base reaction : It is defined as the reaction in which an acid react with a base to give salt and water as a product.
The given chemical reaction is:
This reaction is a precipitation reaction in which the two aqueous solution silver nitrate and sodium chloride combined to give sodium nitrate solution and silver chloride as a precipitate. In precipitation reaction there is no changes in oxidation state of the element.
Hence, the correct option is, (e) precipitation
