Chapter 20: Problem 101

What is the hybridization of the central atom in each of the following molecules? a. \(\mathrm{SF}_{6}\) b. \(\mathrm{ClF}_{3}\) c. \(\mathrm{GeCl}_{4}\) d. \(\mathrm{XeF}_{4}\)

Short Answer

Expert verified
The hybridizations of the central atoms in the given molecules are: a. \(\mathrm{SF}_{6}\): \(\mathrm{Sp^{3}d^{2}}\) b. \(\mathrm{ClF}_{3}\): \(\mathrm{Sp^{3}d}\) c. \(\mathrm{GeCl}_{4}\): \(\mathrm{Sp^{3}}\) d. \(\mathrm{XeF}_{4}\): \(\mathrm{Sp^{3}d^{2}}\)

Step by step solution

01

Identify the central atom for each molecule

First, it is critical to identify the central atom for each molecule. It is the atom that is single in its type within each molecule. Hence, in \(\mathrm{SF}_{6}\), the central atom is S (Sulphur), in \(\mathrm{ClF}_{3}\) is Cl (Chlorine), in \(\mathrm{GeCl}_{4}\) is Ge (Germanium) and in \(\mathrm{XeF}_{4}\) is Xe (Xenon).
02

Count the number of charge centres around each central atom

Next, count the number of charge centres around each central atom. Remember that charge centres include atoms and lone pairs of electrons on the central atom. - In \(\mathrm{SF}_{6}\), there are 6 fluorine atoms connected to the central S atom. - In \(\mathrm{ClF}_{3}\), there are 3 Fluorine atoms connected to the central Cl atom and it also has 2 lone pairs of electrons. - In \(\mathrm{GeCl}_{4}\), there are 4 Chlorine atoms connected to the central Ge atom. - In \(\mathrm{XeF}_{4}\), there are 4 Fluorine atoms connected to the central Xe atom and it also has 2 lone pairs of electrons.
03

Determine the type of hybridization

Then, use the number of charge centres from step 2 to determine the type of hybridization. - In \(\mathrm{SF}_{6}\), there are 6 charge centres meaning the hybridization is \(\mathrm{Sp^{3}d^{2}}\). - In \(\mathrm{ClF}_{3}\), there are 5 charge centres meaning the hybridization is \(\mathrm{Sp^{3}d}\). - In \(\mathrm{GeCl}_{4}\), there are 4 charge centres meaning the hybridization is \(\mathrm{Sp^{3}}\). - In \(\mathrm{XeF}_{4}\), there are 6 charge centres meaning the hybridization is \(\mathrm{Sp^{3}d^{2}}\).

What is nitrogen fixation? Give some examples of nitrogen fixation.

Calcium and magnesium are essential for human life. Explain their importance.

The heaviest member of the alkaline earth metals is radium (Ra), a naturally radioactive element discovered by Pierre and Marie Curie in \(1898 .\) Radium was initially isolated from the uranium ore pitchblende, in which it is present as approximately 1.0 g per 7.0 metric tons of pitchblende. How many atoms of radium can be isolated from \(1.75 \times 10^{8} \mathrm{g}\) pitch- blende \((1 \text { metric ton }=1000 \mathrm{kg})\) ? One of the early uses of radium was as an additive to paint so that watch dials coated with this paint would glow in the dark. The longest-lived isotope of radium has a half-life of \(1.60 \times 10^{3}\) years. If an antique watch, manufactured in \(1925,\) contains 15.0 \(\mathrm{mg}\) radium, how many atoms of radium will remain in 2025\(?\)

Photogray lenses contain small embedded crystals of solid silver chloride. Silver chloride is light-sensitive because of the reaction $$ \mathrm{AgCl}(s) \stackrel{\mathrm{hv}}{\longrightarrow} \mathrm{Ag}(s)+\mathrm{Cl} $$ Small particles of metallic silver cause the lenses to darken. In the lenses this process is reversible. When the light is removed, the reverse reaction occurs. However, when pure white silver chloride is exposed to sunlight it darkens; the reverse reaction does not occur in the dark. a. How do you explain this difference? b. Photogray lenses do become permanently dark in time. How do you account for this?
