The idea is to foretell the formation of a carbonyl compound by the reaction between alcohol and too much pyridinium chlorochromate. An oxidizing agent called pyridinium chlorochromate converts the alcohol group into the 1carbonyl group.
The carbonyl molecule that results from the reaction will depend on the reactant's OH group. Pyridinium chlorochromate [PCC] converts primary OH to aldehydes, whereas it converts secondary OH to ketones, and oxidation of tertiary OH has little effect. Alcohols and pyridinium chlorochromate [PCC] react to create a carbonyl molecule.
From primary alcohols to aldehydes and from secondary alcohols to ketones, pyridinium chlorochromate oxidizes alcohols one step up the oxidation ladder. pyridinium chlorochromate will not oxidize aldehydes to carboxylic acids, in contrast to chromic acid. Comparable to Pyridine (the Collins reagent) and CrO3 will both oxidize primary alcohols to aldehydes. Here are two instances of pyridinium chlorochromate being used.

Answer: All the points apply for colloids.
Explanation: This question can be answered only by looking at the properties of colloids:
- The particle size of these systems range from 1nm to 1mm.
- These are generally considered as heterogeneous mixtures but have some properties of homogeneous mixtures. There is some physical boundary present between solute and solvent.
- These solutions cannot be separated by ordinary filtration.
- Tyndall effect: This effect is generally seen in colloidal solutions or solutions having very fine suspension. This effect is basically the scattering of light by the particles. This effect can be seen in the sky when sunlight is scattered by clouds.
- These solutions have small particle size thus it cannot be seen from bare eyes, thus we need optical microscope.
- Cloud, Milk, Fog and Smoke are some of the examples of Colloidal solutions.
These properties enlisted above show that all the points given in the question are correct for colloidal solutions.
C and D are correct. This is the process of replication, and option E refers to repetition.
