Answer:
a) C₆H₁₂O₆, CH₃OH, CH₃CH₂OH
Step-by-step explanation:
For a solution to be conductive, it requires to have electrolytes, that is, species that dissociate into ions and carry electrical charges.
Which of the following substances would be a poor choice for making conductive solutions?
a) C₆H₁₂O₆, CH₃OH, CH₃CH₂OH
These species are formed exclusively by covalent bonds and they are non-electrolytes, that is, they practically do not form ions in water. Therefore, a solution containing these species would be poorly conductive.
b) HCl, KBr, HNO₃
The species are formed by ionic and covalent bonds and are electrolytes. Thus, their solutions are conductive.
c) NaOH, KOH, LiOH
The species are formed by ionic and covalent bonds and are electrolytes. Thus, their solutions are conductive.
