Chemistry 112
Problem 3 (requires the answers from 1 and 2 that are already provided) Pre-Laboratory Questions 1. The solubilities of four unknown compounds (A, B, C, and D )were tested in (CH CH CH CH-CH2). The results of the solubility tests are provided belWater and 1-hexene data, determine whether compounds A, B, C, and D are polar or nonpolar ts are provided below polar or nonpolar . From the solubility Solubility in water insoluble soluble soluble soluble Solubility in 1-hexene soluble insoluble insoluble insoluble lar or Nompolar Compound Olar 2. The electrical conductivities of the unknown compounds (A, B, C, and D) were determined using a conductivity detector. The results of the conductivity tests are provided below. Determine whether compounds A, B, C, and D are strong, weak, or nonelectrolytes. Compound Strong/Weak/Nonelectrolyte Conductivity Test LED does not light LED does not light LED lights brightly LED lights dimly Stoon 49

Explanation / Answer

Solution :-

As we know compound C shows strong LED light that means its strong electrolyte therefore the from the list of the unknown we have HClO2 and LiCl

HClO2 is weak acid therefore it do not dissociate 100 % tehrefore it shows dim light to the LEd

but LiCl is the strong electrolyte because its ionic compound therefore it shows the bright LED light

Therefore C= LiCl and D= HClO2

From unknown A and B the A is soluble in water that means its polar compound

Therefore A is HO-CH2-CH2-NH2 is polar compound hence it is soluble in the

Reaining

is the B that is methyl cyclopentane which is insoluble in water .
