Question

Identify the odd term out and explain.
Sugar, salt, baking soda, blue vitriol

Answer 1

In order to identify the odd term out from the following compounds, we must consider the constituents of all the compounds which make them different from each other. For example in the case of salt it is an ionic compound made up of sodium and chlorine.

Complete answer:
From the given substances: sugar, salt, baking soda, blue vitriol
Sugar is a soluble carbohydrate that is an organic compound. It is made up of sucrose that is a disaccharides composed of glucose and fructose. Tissues of most plants are the source of sugar. Simple sugars are found in honey and fruit. It gets concentrated in sugarcane and sugar beet, making them ideal for efficient commercial extraction to make refined sugar.
Salt, that is table salt having the chemical name sodium chloride. Chemical formula of chemical chloride is $NaCl$ . It is an ionic crystal compound. It is essential for life in general. And its saltiness is one of the basic human tests.
Baking soda, it is also an inorganic compound having the chemical name sodium bicarbonate. Chemical formula of sodium bicarbonate is $NaHC{O_3}$ . It acts as a leavening agent. It is most used in cooking especially in baking products.
Blue vitriol, it is also an inorganic compound, a salt having the chemical name copper sulphate. Chemical formula of copper sulphate is $CuS{O_4}.5{H_2}O$ . It has the appearance of blue color crystals. It is used as a moderate, insecticide, fungicide and in engraving.
So all of them are inorganic salt except sugar. Sugar is an organic compound.
Hence, sugar is an odd term from all of the above.

Note:
Monosaccharides in a closed-chain form are able to form glycosidic bonds with other monosaccharides that create disaccharides for example sucrose and polysaccharides for example starch. Enzymes must hydrolyse or otherwise break these glycosidic bonds before such compounds become metabolized.
