Question

Which one of the following substances would be the most soluble in C6H6 ? Group of answer choices CO2 all of these can dissolve C6H6 C10H22 S8 (sulfur) SiO2

Answer 1

Answer:

C10H22

Explanation:

C6H6 is the molecular formula for Benzene. Benzene is an aromatic hydrocarbon which is obtained from the destructive distillation of coal. Benzene is a colourless volatile liquid with a sweet smell. Its vapor is highly toxic and mildly carcinogenic. It is highly inflammable. Benzene is nonpolar which is insoluble in water. Since benzene is insoluble in water , it will take an insoluble compound to be soluble in benzene since "like dissolves like".

From the options given:

C10H22 which is the molecular formula for Decane would be the most soluble in C6H6. This is because Decane is an alkanes which is an aliphatic hydrocarbon and their physical properties increases with increasing molar mass ( i.e melting points, boiling points , density, polarity) etc. The first mfour member of the family are gases. non-polar liquid starts with th fifth member of the family which is pentane and from hexadecane onwards the members are solids at room temperature. Thus, decane is a non-polar hydrocarbon which is insoluble in water but soluble in benzene
