Nonelectrolytes are compounds that do not ionize at all in solution. As a result, solutions containing nonelectrolytes will not conduct electricity. Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. 

Sugar molecules are covalent compounds which doesn't dissociates into ions so they will not conduct electricity in solution and are non-electrolyte.
Also, water has very low ionisation constant so it dissociates very low and pure water is consists almost entirely of molecules. As number of ions are very less in pure water so normally it will not conduct electricity and its non-electrolyte.

 Molecules will be found in a liquid compound which is a non-electrolyte. For example, glucose is a non electrolyte. It does not dissociates in aqueous solution. Hence, in aqueous glucose solution, we can find glucose molecules. Another example of non electrolyte is urea.

Nonelectrolytes are compounds that do not ionize at all in solution. As a result, solutions containing nonelectrolytes will not conduct electricity. Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. A common example of a nonelectrolyte is glucose. Liquid carbon tetrachloride is also a nonelectrolyte.

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. The dissolved electrolyte separates into cations and anions, which disperse uniformly through the solvent. Electrically, such a solution is neutral.

Electrolytes are always ionic in nature.
Electrolytes in aqueous solution dissociate into cation and anion respectively.

An electrochemical cell converts chemical energy to electrical energy. An electrochemical cell has two electronic conductors such as metal plates or carbon rods dipped into an electrolytic or ionic conductor which is an aqueous electrolytic solution or a pure liquid of an electrolyte.

Statement 1: Benzene is a non electrolyte. Its molecules do not undergo dissociation.
Statement 2: A good electrolyte has charged ions that carry the electric current.
Statement 1 is not correct but Statement 2 is correct.

Statement I : In water, a  nonelectrolyte does not ionize.
For example, urea and glucose are non-electrolytes. They do not ionize in water.
Statement II : The ionic solution does conduct electricity.
Thus aqueous $NaCl$ solution conducts electricity as $NaCl$ dissociates into $\displaystyle Na^+$ ions and chloride $\displaystyle Cl^-$ ions.
$\displaystyle NaCl \rightleftharpoons Na^+ +  Cl^- $.
Statement I is True, Statement II is False

If the electrodes were put in a saturated solution of glucose which is dissolved in water, light bulb would remain dark.
This indicates that no electricity is passing through aqueous glucose solution.
Glucose is a non electrolyte. Hence, in aqueous solution of glucose, no ions are present. Hence, it cannot conduct electricity.
