This question seems unclear as some fragments were repeated. However, the comprehensive question, in addition to the explained answers to fill the gap can be found in the explanation section. The answers are typed in BOLD.
Explanation:
It is _FALSE_ that when chloroform, CHCl3, is dissolved in water, a conducting solution results. This is because chloroform, CHCl3 is a _NON-ELECTROLYTE_ that _DOES NOT_ support the movement of charge.
In contrast to an electrolyte, a NON-ELECTROLYTE is a substance that does not ionize or dissociate into ions (charged atoms) when dissolved in water. Since they do not ionize, they also do not conduct electricity. An example is the Chloroform (CHCl3) described in this question.
