    NO2 makes the ring electrons rich at ortho and para position  
  • b)
    NO2 withdraws electrons from meta position  
  • c)
    NO2 donates electrons at m-position

"Replacement of" can refer to a variety of things. Here are a few examples:

1. Replacement of a product: This refers to finding a new item to replace an old or broken one. For example, if your phone stops working, you may need to find a replacement phone.

2. Replacement of a part: This refers to replacing a specific component of something. For example, if a car's engine is not working properly, you may need to replace a specific part, such as the spark plugs.

3. Replacement of a person: This refers to finding a new person to take over a role or position. For example, if an employee leaves a company, the company may need to find a replacement for that person.

4. Replacement of a habit or behavior: This refers to changing or substituting a specific action or routine with a different one. For example, if you want to improve your health, you may need to replace unhealthy eating habits with healthier ones.

5. Replacement of a system or technology: This refers to upgrading or updating a current system or technology with a newer or more advanced version. For example, if a computer system is outdated, it may need to be replaced with a newer model.

Overall, "replacement of" refers to the act of finding or substituting something or someone with an alternative.

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescence microscopy.Q. Wavelength of electron as wave at accelerating voltage 200 keV is
