BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Water is a polar molecule made of one oxygen atom connected to two hydrogen atoms through polar covalent bonds. Water is polar, meaning the atoms in the covalent bonds share electrons unequally.

Detailed explanation-2: -The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

Detailed explanation-3: -Polar species are soluble in water, while nonpolar species are soluble in oils and fats. Covalent solubility uses the like dissolves like rule. This means that substances with the same type of polarity will be soluble in one another.

Detailed explanation-4: -Solubility. Compare how well polar, slightly polar, and nonpolar liquids dissolve substances. In our experiment in Activity 4, we found that water dissolves ionic salts and polar covalent compounds such as alcohol. We also saw that water is far less effective as a solvent for nonpolar covalent compounds such as oil.

Detailed explanation-5: -The difference in electronegativities between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms. Water molecules attract or are attracted to other polar molecules. Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.
