The first step is the draw out the molecules in question to understand what is happening in the reaction. You can see that the bromine atom has been substituted for an alcohol group (OH) in the enthane mo...

Entropy is the level of disorder in the universe. The more disordered something is, the higher its entropy. Molecules in solids ae specifically arranged and vibrating, hence the level of disorder is low, ...

Chlorine molecules are smaller than bromine molecules in size, therefore, the van der Waals forces (intermolecular forces) are weaker between Cl2 molecules than compared to Br2 molecules.

Ionization energy is the energy required to remove the most loosely bound electron from an atom. As the nuclear charge of an atom increases and the size of an atom decreases, the ionization energy increas...

(Talk about needing to memorise colour tests for base metals and tests for Halides) The compound is KI (potassium Iodide) because potassium compounds burn with a lilac flame, and production a pale yellow ...
