Answer:
The disadvantages or the limitations are as follows:
Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons
Arrow and line diagrams: Does not say much of the possible properties of the molecule.
Written electron configurations: no 3D representation of the molecule or the atom

The statement of letter B, the collisions of particles with one another is completey elastic, is true about Kinetic Molecular Theory. Elastic collisions means that there is no energy transfer between the particles.
Answer:
There are three main components to kinetic theory: No energy is gained or lost when molecules collide. The molecules in a gas take up a negligible (able to be ignored) amount of space in relation to the container they occupy.

Answer:
Part a: The IR spectrum is not sufficient due to the similar radical group presence in both product and reactants.
Part b: Mass Spectrum data is required in addition to the IR data for confirming the presence of recrystallized product.
Part c: The additional data is consistent with the expectations as the data is in support of that.
Explanation:
Part a
Acetanilide has a characteristic IR peak at around 3100-3200 cm^-1 (N-H Stretching) and 1500-1680 cm^-1 (C=O Stretching). Since a similar radical group (
) is present in the 4-bromoacetanilide, thus it is difficult to affirm the presence of the product solely on the basis of IR spectrum.
Part b
Mass Spectral data will affirm the presence of recrystallized product with certainty.
Part c
4-bromoacetanilide will have
peak at two points (213 & 215) corresponding to the two Bromine isotopes (79 & 81).
Also parent peak at 171 (
=43) will be in 49:51 due to presence of Bromine atoms.
