The noble gas core for Mo should be identified using the concept of electron configuration. Concept Introduction: An orbital is an area of space in which electrons are orderly filled. The maximum capacity in any type of orbital is two electrons. An atomic orbital is defined as the region of space in which the probability of finding the electrons is highest. It is subdivided into four orbitals such as s , p , d a n d f orbitals which depend upon the number of electrons present in the nucleus of a particular atom. There are three basic principles in which orbitals are filled by the electrons. 1. Aufbau principle: In German, the word 'aufbau' means 'building up'. The electrons are arranged in various orbitals in the order of increasing energies. 2. Pauli exclusion principle: An electron does not have all the four quantum numbers. 3. Hund’s rule: Each orbital is singly engaged with one electron having the maximum same spin capacity after that only pairing occurs. The electron configuration is the allocation of electrons of an atom in atomic orbitals. Electronic configuration of a particular atom is written by following the three basic principles.

Interpretation Introduction
Interpretation:
The noble gas core for Mo should be identified using the concept of electron configuration.
Concept Introduction:
An orbital is an area of space in which electrons are orderly filled. The maximum capacity in any type of orbital is two electrons. An atomic orbital is defined as the region of space in which the probability of finding the electrons is highest. It is subdivided into four orbitals such as s,p,dandf orbitals which depend upon the number of electrons present in the nucleus of a particular atom.
There are three basic principles in which orbitals are filled by the electrons.
1. Aufbau principle: In German, the word 'aufbau' means 'building up'. The electrons are arranged in various orbitals in the order of increasing energies.
2. Pauli exclusion principle: An electron does not have all the four quantum numbers.
3. Hund’s rule: Each orbital is singly engaged with one electron having the maximum same spin capacity after that only pairing occurs.
The electron configuration is the allocation of electrons of an atom in atomic orbitals. Electronic configuration of a particular atom is written by following the three basic principles.

Expert Solution & Answer
Answer to Problem 3.1KSP
The noble gas core for Mo is (b) Kr
Explanation of Solution
Reason for correct option
Mo is present in VIB group of the periodic table. Its atomic number is 42. Its outermost electron configuration is [Kr]4d55s1. It is present in 5th row of the periodic table. Hence the noble gas core for Mo should be present in 4th row of the periodic table which is krypton (Kr-36).
Therefore, option (b) is correct.
Reasons for incorrect options:
Ar is present in 3th row of the periodic table whereas Mo is present in 5th row of the periodic table. Hence, Ar is lesser noble gas core for Mo. Xe is present in 5th row of the periodic table. Hence, Xe is greater noble gas core for Mo. Ne is present in 2th row of the periodic table whereas Mo is present in 5th row of the periodic table. Hence, Ne is lesser noble gas core for Mo. Rn is present in 6th row of the periodic table whereas Mo is present in 5th row of the periodic table. Hence, Rn is greater noble gas core for Mo.
Therefore, the options (a), (c), (d) and (e) are incorrect.
Conclusion
The noble gas core for Mo is identified using the concept of electron configuration.

Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.

molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will
contribute to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.

Some important Notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to draw bonds carefully to show important geometric relationships between substituents.
Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the
ring structure. You can add any substituents using the pencil tool in the usual way.
