16. In what respect is a triple bond different from a singular or double bond?
a) The single and double bonds are usually covalent, but the triple bond is ionic.
b) Triple bonds can form between any two elements, single and double bonds cannot.
c) There is no difference between any of these bonds as they are all covalent.
d) None of these statements are correct.
18. Any discussion of polarity and polar bonds is likely to include the terms partial negative (0 - ) and partial positive (0 +). Why?
a) Polarity is caused by the presence of ionic bonds that are not quite completely ionic, therefore the charges are not quite full ion charges.
b) Polarity is really due to the gain and loss of electrons; therefore, the partial charges are very close to being complete charges
c) Polarity is due to the uneven sharing of electrons; the atoms involved do not completely gain or lose electrons which produces a partial charge.
d) Polarity is a theoretical concept and the idea of partial charges is used to separate the theoretical from the proven.
