<u>Answer:</u> The correct answer is Xenon (Xe).
<u>Explanation:</u>
Noble gases are defined as the gases which have fully filled electronic configuration or stable electronic configuration.
From the given options:
<u>Option 1:</u> Oxygen (O)
The atomic number of this element is 8.
Electronic configuration of this element:
As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.
<u>Option 2:</u> Nitrogen (N)
The atomic number of this element is 7.
Electronic configuration of this element:
As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.
<u>Option 3:</u> Chlorine (Cl)
The atomic number of this element is 17.
Electronic configuration of this element:
As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.
<u>Option 4:</u> Xenon (Xe)
The atomic number of this element is 54.
Electronic configuration of this element:
As, this is a stable electronic configuration. Thus, it is considered as a noble gas.
Hence, the correct answer is Xenon (Xe).
Answer: There are 4 monofluoro derivatives of methylcyclopentane. Only 1 derivative has flourine atom attached to a primary carbon.
Explanation: The compound methylcyclopentane has 1-primary carbon, 4- secondary carbons and 1-tertiary carbon.
1) Primary carbon (1°): In this the carbon atom is attached directly to only one carbon atom.
2) Secondary carbon (2°): In this the carbon is attached directly to two carbon atoms.
3) Tertiary Carbon (3°): In this the carbon is attached directly to three carbon atoms.
The monofluoro derivatives are shown in the image below.
Structure B is the only derivative which has fluorine attached to primary carbon atom.
