Chirality in molecules refers to the property of being non-superimposable on their mirror images. Chiral molecules exhibit optical activity, while achiral molecules are optically inactive.

Haloalkanes have low solubility in water because energy is required to overcome attractions between haloalkane molecules and break hydrogen bonds in water. The new attractions between haloalkanes and water molecules are weaker than the original hydrogen bonds in water, resulting ...

Bromo, iodo, and polychloro derivatives of hydrocarbons are heavier than water, and their density increases with the number of carbon atoms, halogen atoms, and the atomic mass of the halogen atoms.

The symmetry of para-isomers allows for a better fit in the crystal lattice, resulting in higher melting points compared to their ortho- and meta-isomers.

Boiling points of alkyl halides decrease in the order: RI > RBr > RCl > RF. This trend is attributed to the increase in size and mass of the halogen atom, leading to stronger van der Waals forces.
