Question

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.

Answer 1

Whereas ionic bonds form a SALT, covalent bonds between atoms form a MOLECULE.
These covalent bonds have a characteristic bond LENGTH and become stronger and more rigid
when two pairs of electrons are shared in a DOUBLE BOND.
Equal sharing of electrons yields a NONPOLAR covalent bond.
These POLAR covalent bonds should not be confused with the
weaker NONCOVALENT bonds that are critical for the three
dimensional structure of biological molecules and for
interactions between these molecules.
