The substance that must be present in an aqueous solution for it to conduct an electric current and the general class of compound that form conductive solution is to be determined. Concept introduction: A solution is a combination of two parts: solute and solvent. The solute is the substance that is present in small quantity and solvent is the substance in which solute is dissolved. When water acts as a solvent then it is known as an aqueous solution. An electrolyte is a substance that conducts electricity when it is dissolved in water. Ionic compounds are the compounds that are composed of charged ions. There are held together by electrostatic forces. Example of an ionic compound is NaCl .

The total number of carbons in the parent chain is incorrect. Review the reaction conditions including starting materials and/or
intermediate structures and recount the number of carbon atoms in the parent chain of your structure.

Using a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40.
a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L)
b) Calculate the molar absorptivity, a, of the 1645 cm-1 band
c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c
d) Calculate x for the 1645 cm-1 band
Convert 1.38 eV into wavelength (nm) and wavenumber (cm-1) (c = 2.998 x 108 m/s; h = 6.626 x 10-34 J*s).
