(a)
Interpretation:
The compound having highest melting point should be determined.
Concept introduction:
The binary hydrides are compounds which contain hydrogen and one other element. Binary hydrides can be classified as ionic, covalent or metallic. Covalent hydrides have lowest melting and boiling points because they have relatively weak intermolecular forces between molecules. Ionic hydrides have higher boiling and melting points, because they have stronger ionic interactions between molecules.
(b)
Interpretation:
The compound having lowest boiling point should be determined.

(Note: it's not equal to the difference in chemical shifts.) Round your answer to 2 significant digits, and be sure it has an appropriate unit symbol. = O O a will shift left, c will shift right. O a will shift right, c will shift left. a and c will both shift left, with more space between them. Suppose a new spectrum is taken with a 500 MHz spectrometer. What will be true about this new spectrum? O a and c will both shift left, with less space between them. O a and c will both shift right, with more space between them. O a and c will both shift right, with less space between them. Which protons have the largest energy gap between spin up and spin down states?
