Question

Which one of the following will not conduct electricity?
A.Lemon Juice
B.Vinegar
C.Tape water
D.Vegetable oil

Answer 1

Hint:The substances that conduct electricity are known as conductors and those who do not allow electricity to pass through them are known as insulators.
Conductors allow passing the electricity through them with the help of the charge particles (ions, electrons, protons). When current is applied across the ends of a conductor charged particles start moving in a definite direction and current starts flowing through it.

Complete step by step answer:
Lemon juice mainly consists of citric acid and thus is acidic. And therefore, when it is dissolved in water it breaks down into charged particles, anions, and cations. Which helps it to conduct electricity.
Vinegar is acetic acid and thus acidic. It breaks into acetate anion and hydrogen cation. Which is responsible for the conduction of electricity.
Tape water contains many metal cations and other anions such as fluoride, chloride, etc. in the form of impurity, and therefore it can conduct electricity.
Vegetable oil is basically made of organic compounds and does not have any charged particles and due to absence of charged particles, vegetable oil cannot conduct electricity.
Hence, the correct option is D. Vegetable oil cannot conduct electricity.


Note:
Vegetable oils are composed of triacylglycerols (about 92 to 98 in percentage). Vegetable oils are extracted from oilseeds. They are primarily for human consumption but can be used for human consumption as well. Some of the common vegetables used in the food industry are sunflower oil, groundnut oil, etc. These are completely organic compounds and do not contain any kind of charged particles. Some of the vegetable oils having trans-fat can lead to cholesterol accumulation in the body which can lead to various heart-related diseases.
