Aldehyde is more acidic then ester, as ther is +R effect of -OMe group in ester, it decreases the electron withdrawing power of carbonyl group.for second case it is ester.but for 3rd case, the (alfa H) is attached with two carbonyl group.
so the order of acidity is ¡>¡¡¡>¡¡
so the order of acidity is ¡>¡¡¡>¡¡

N2O4(g)⇌2NO2(g)
One mole of N2O4 gives 2 moles of NO2 gas. The pressure of the gas increases. Upon compressing the gaseous mixture, there is a change in an equilibrium concentration & backward reaction is favoured. This is according to Le Chatlier's Principle

- The above reaction is an example of E2 elimination.
- For E2 elimination both the leaving group must be anti w.r.t each other in the adjacent carbon atoms.
- In option C, we get this requirement of anti geometry of the Br atoms, so it undergoes reaction.

Explain resonance with example?

Chirag Nambiar answered • Nov 21, 2024 |
Understanding Resonance
Resonance is a phenomenon that occurs when a system is subjected to an external force at a frequency that matches the system's natural frequency. This matching causes the system to oscillate with significantly greater amplitude, leading to enhanced energy transfer.
Key Characteristics of Resonance:
Example of Resonance:
A classic example of resonance can be observed in a swing.
Applications of Resonance:
In summary, understanding resonance is vital in various fields, from music to engineering, ensuring systems function efficiently without risk of damage.

Key Characteristics of Resonance:
- Natural Frequency: Every system ... more
- Driving Frequency: This is the frequency of the external force applied to the system. When it matches the natural frequency, resonance occurs.
- Amplitude Increase: At resonance, the amplitude of oscillation increases dramatically, which can lead to potential damage if not controlled.
Example of Resonance:
A classic example of resonance can be observed in a swing.
- Natural Frequency: A swing has a specific natural frequency determined by its length and the force of gravity.
- Driving Force: When a person pushes the swing at regular intervals (the same frequency as the swing's natural frequency), the swing goes higher and higher.
- Result: If the pushes are timed perfectly, the swing resonates, leading to increased height and energy.
Applications of Resonance:
- Musical Instruments: Instruments like guitars and violins use resonance to amplify sound.
- Engineering: Engineers must consider resonance in structures like bridges to avoid catastrophic failures.
In summary, understanding resonance is vital in various fields, from music to engineering, ensuring systems function efficiently without risk of damage.

- c)it can be reduced to a single equation and so a solution does not exist

Chirag Nambiar answered • Aug 05, 2024 |
Del Operator:
The `del` operator in Python is used to delete an object from memory. It removes a reference to an object, allowing the garbage collector to reclaim the memory used by that object if there are no other references to it. This can be useful for freeing up memory or cleaning up resources when they are no longer needed.
