(a)
Interpretation:
The reason for given incorrect atomic orbital and how it needs to be corrected has to be given.
Figure 1
Concept Introduction:
Electron configuration: The complete description of the atomic orbitals occupied by all the electrons in an atom or monoatomic ion is known as its electron configuration.
(b)
Interpretation:
The reason for given incorrect atomic orbital and how it needs to be corrected has to be given.
Figure 2
Concept Introduction:
Hund’s rule: Each orbital must be singly occupied before any orbital is occupied. All the electrons in singly occupied orbitals have same spin.
(c)
Interpretation:
The reason for given incorrect atomic orbital and how it needs to be corrected has to be given.

- Consider this molecule: How many H atoms are in this molecule? How many different signals could be found in its 'H NMR spectrum? Note: A multiplet is considered one signal. ☐arrow_forwardStudy this 'H NMR spectrum, and then answer the questions about it in the table below. Check 1.0- 0.5- 0.0 10.0 9.0 8.0 7.0 6.0 5.0 4.0 3.0 2.0 1.0 0.0 What unit symbol should be written on the horizontal axis? What is the chemical shift & of the doublet? If there is no doublet, just check the box instead. Give your answer to 2 significant digits. What is the chemical shift of the signal immediately upfield of the doublet? If there is no doublet, or no signal upfield of it, check the box instead. What is the chemical shift & of the least deshielded proton? If you can't tell without more information, check the box instead. 血 8 = ☐ There is no doublet. 8 = ☐ No such signal. 8 = 0 Need more information.arrow_forwardhow many moles of H2O2 are required to react with 11g of N2H4 according to the following reaction?

Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it. Round your answer to 2 significant digits. 00 rise ☐ x10 fall yes no ☐ atm G Ar 1arrow_forward
