Which of the following represents a non-electrolyte? a) (CH 3 ) 2 NH 2 b) NaOH c) HIO 3 d) C 2 H 5 OH e) CsNH 2

Which of the following represents a non electrolyte? So remember, the examples that we have of non electrolytes have been water, sugar, alcohols, and other non ionic compounds. Of this description, which one could we find out of these choices? So we have a which is composed of carbons, nitrogens, and hydrogens. B is out because that's NaOH, a strong base, which would be a strong electrolyte. Here we have h I o three. It's a covalent compound beginning with hydrogen. And remember, from our earlier videos, this was the definition of an acid. Now whether it's a strong acid or a weak acid, it doesn't matter. Acids are either strong or weak electrolytes, not non electrolytes. Next, we have c 2 h5 o h. It's a compound composed of carbons and hydrogens connected to o h, which is a definition of an alcohol. And then the last one, this is a soluble ionic compound since it's made up of cesium, which is from group 1 a. Remember your solubility rules. Now we're not quite sure what a is, but we definitely know that d is the answer because it represents an alcohol. And we know that alcohols are one of the groups we classified as being non electrolytes. So here the answer would be option d.

Verified step by step guidance

Understand the concept of electrolytes and non-electrolytes: Electrolytes are substances that dissolve in water to produce a solution that conducts electricity. Non-electrolytes do not produce ions in solution and therefore do not conduct electricity.

Identify the chemical nature of each compound: a) (CH3)2NH2 is an amine, b) NaOH is a strong base, c) HIO3 is an acid, d) C2H5OH is an alcohol, e) CsNH2 is an amide.

Determine the ionization behavior in water: NaOH dissociates completely into Na+ and OH- ions, making it an electrolyte. HIO3, being an acid, also ionizes in water, making it an electrolyte.

Consider the molecular structure of C2H5OH (ethanol): Ethanol is a covalent compound that does not ionize in water. It dissolves but does not produce ions, classifying it as a non-electrolyte.

Conclude that C2H5OH is the non-electrolyte among the given options, as it does not produce ions in solution and therefore does not conduct electricity.
