Answer to Problem 4E
Lewis dot symbols for all the given elements are drawn below.
.
Explanation of Solution
Ge, Sb, Se and Br have 4, 5, 4, 6 and 7 valence electrons respectively. Accordingly Lewis dot structures are shown as follows:
(b)
Interpretation Introduction
Interpretation:
Lewis structures for GeH4, SbH3, H2Se and HBr must be drawn.
Concept Introduction :
Ge, Sb, Se and Br bond with 4, 3, 2 and 1 hydrogen respectively to form the corresponding covalent hydrides.

Expert Solution
Answer to Problem 4E
Lewis structures for all the hydrides are shown below.
Explanation of Solution
Ge has 4 valence electrons and bonded with 4 hydrogens. There is no lone pair of electrons.
Sb has 5 valence electrons and formed 3 covalent bonds with 3 hydrogens. There are one lone pair electrons on Sb atom.
Se has 6 valence electrons and bonds with 2 hydrogens. There are 2 lone pairs of electrons on Se atom.
Br has 7 valence electrons and bonds with 1 hydrogen. There is 3 lone pair of electrons on Br atom.
Thus, the Lewis structures are represented as follows:
(c)
Interpretation Introduction
Interpretation:
Pattern for number of hydrogen atoms in GeH4, SbH3, H2Se and HBr must be explained.
Concept Introduction :
Ge, Sb, Se and Br have valence electrons as 4, 5, 6 and 7 respectively. Thus, the vacancies are 4, 3, 2 and 1 respectively.
(c)
Expert Solution
Answer to Problem 4E
Number of hydrogens gradually decreases from Ge to Br.
Explanation of Solution
Ge has 4 valence electrons and bonded with 4 hydrogens. Sb has 5 valence electrons and valency 3 and formed 3 covalent bonds with 3 hydrogen atoms.
Se has 6 valence electrons and valency 2 and bonds with 2 hydrogens.
Br has 7 valence electrons and valency 1 and bonds with 1 hydrogen.
Thus, the number of hydrogen atoms decreases from Ge to Br.

- Recent advancements in liquid chromatography include the development of ultrahigh pressure liquid chromatography (UHPLC) and an increased use of capillary columns that had previously only been used with gas chromatography. Both of these advances have made the development of portable LC systems possible. For example, Axcend Corp. makes a portable system that uses a capillary column with an internal diameter of 150-μm-that is packed with 1.7-um stationary phase particles. In contrast, a traditional LC column has a 4.6 mm internal diameter and utilizes 5-um stationary phase particles. a) Explain one advantage that is afforded by the use of a capillary column in liquid chromatographic separation.

This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is desirable to separate LMWH from higher molecular weight heparins. The method of choice to do this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion chromatographic run. Peaks ranging from A to J are clearly distinguishable.
