26 which substance is an electrolyte? (1) c6h12o6(s) (3) naoh(s)(2) c2h5oh(l) (4) h2(g)

Electrolytes conduct electricity because they produce + and – ions in water 
C6H12O6 and CH3CH2OH organic no ions
C6H12O6 and HCl sugar and hydrochloric acid 
NaOH and HCl yields Na+1 ion and Cl-1 ion to conduct electricity
NaOH and CH3CH2OH

Hope this helps. :)

Option (3) is the correct answer.

Explanation:

When a compound dissolved in solution dissociates into ions then the solution is able to conduct electricity is known as an electrolyte.

This means that ionic molecules are able to conduct electricity because they are able to dissociate into ions.

Thus, we can see that out of the given options NaOH is ionic in nature hence, it is an electrolyte.

Whereas , , and are not ionic in nature therefore, they are not electrolyte.
