1. which of the following is the least basic? a. cola b. lye c. water d. ammonia 2. water is considered the universal solvent because it can dissolve a. elements. b. everything. c. polar molecules. d. nonpolar molecules. which of the following is not an organic compound? a. table sugar b. copper c. vegetable oil d. dna

1). Cola is least basic.

               2). Water is a polar solvent because it can dissolve                                       polar molecules.

               3). Copper is not an organic compound.

Explanation:

1).   Substances or solutions that have value of pH less than 7 are known as acidic. Whereas substances with pH value greater than 7 are known as base.

For example, all the carbonated beverages like cola, limca, pepsi etc are all acidic in nature as they have pH value less than 7.

Whereas  water is a neutral substance as its pH is equal to 7. On the other hand, lye and ammonia are very basic in nature.

Hence, out of the given options, cola is the least basic.

2).   Water is a polar molecule because of difference in electronegativity of hydrogen and oxygen. This causes a partial positive charge on hydrogen atom and partial negative charge on oxygen atom.

Since, it is known that like dissolves like. Hence, water is able to dissolve polar molecules.

For example, KCl is soluble in water as it dissociate into ions upon dissolution.

3).   Organic compounds are the substances that contain carbon and hydrogen atoms.

For example, formula of table sugar is .

As there are carbon and hydrogen atoms present so, table sugar is an organic compound.

Hence, we can conclude that out of the given options copper is not an organic compound.

the answer is trees if i'm not mistaken
