Question

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once.
Whereas ionic bonds form a(n)_________, covalent bonds between atoms form a(n)__________. These covalent bonds have a charachteristic bond ______________and become stronger and more rigid when two pairs of electrons are shared in a(n) __________. Equal sharing of electrongs yields a(n)_____________ covalent bond. If one atom participating in the bond has a stronger affinity for the electron, this produces a partial negative charge on one atom and a partial positive charge on the other. These_______ covalent bonds should not be confused with the weaker_______________ bonds that are critical for the three-dimensional structure of biological molecules and for interactions between these molecules.

Explanation / Answer

Whereas ionic bonds form charge, covalent bonds between atoms form a molecule. These covalent bonds have a characteristic bond polar and become stronger and rigid where two pairs of electrons are shared in a double bond. Equal sharing of electrons yield a non polar covalent bond. If one atom participating in the bond has a stronger affinity for the electron, this produces a partial negative charge on one atom and a partial positive charge. These polar covalent bonds shouldn’t be confused with the weaker ionic bond that are critical for the 3 dimensional structure of biological molecules and for interactions between these molecules.
