To find: para-nitroaniline is an order of magnitude less basic than meta-nitroaniline. Find the reason for the given statement
Find the delocalization behavior of para-nitroaniline
(b)
Interpretation: The difference in basicity between ortho- or para- and meta-nitroanilines has to be discussed
Concept Introduction:
Resonance is a mental exercise and method within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules. The net sum of valid resonance structures is defined as a resonance hybrid, which represents the overall delocalization of electrons within the molecule. A molecule that has several resonance structures is more stable than one with fewer. If the delocalization of electrons within molecules is more, the compound is less basic and vice versa.
To find: Finding the basicity of ortho-nitroaniline which is closer in value to meta- or to para-nitroaniline
Find the delocalization behavior of ortho-nitroaniline

- Speaking of composite materials, indicate the correct option:(A). Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forwardWhen natural light falls perpendicularly on a material A, it has a reflectivity of 0.813%.
