Para-isomers of dihalobenzenes generally have higher melting points compared to their ortho- and meta-isomers due to stronger intermolecular forces in the para-arrangement. In para-isomers, the halogen atoms are positioned opposite each other, allowing for more efficient packing of molecules in the solid state. This arrangement maximizes van der Waals forces, leading to a stronger crystal lattice and higher melting points. In contrast, the ortho- and meta-isomers have less favorable molecular packing, resulting in weaker intermolecular forces and lower melting points. The more symmetrical para-arrangement enhances the cohesive forces between molecules, contributing to the observed difference in melting points.
The density of bromo, iodo, and polychloro derivatives of hydrocarbons is generally higher than that of water. This is because halogen atoms in these compounds contribute to increased molecular mass and packing efficiency, resulting in higher density. Chlorine, bromine, and iodine have higher atomicRead more
The density of bromo, iodo, and polychloro derivatives of hydrocarbons is generally higher than that of water. This is because halogen atoms in these compounds contribute to increased molecular mass and packing efficiency, resulting in higher density. Chlorine, bromine, and iodine have higher atomic masses than hydrogen, leading to denser molecules. Additionally, the larger size of halogen atoms enhances van der Waals forces between molecules, further increasing density. The specific arrangement of halogens in polychloro derivatives can influence density variations. Overall, the molecular mass and arrangement of halogens contribute to the elevated density of these derivatives compared to water.
Zinc (Zn), Cadmium (Cd), Mercury (Hg), and Copernicium (Cn) are not regarded as transition elements despite having the electronic configuration (n-1)d¹⁰ ns² because they do not exhibit the characteristic properties associated with transition metals.

Zinc (Zn), Cadmium (Cd), Mercury (Hg), and Copernicium (Cn) are not regarded as transition elements despite having the electronic configuration (n-1)d¹⁰ ns² because they do not exhibit the characteristic properties associated with transition metals. Transition elements are defined by their incomplete d subshells in the neutral atom or ions. However, Zn, Cd, and Hg of Group 12 have full d¹⁰ configurations in their ground state and common oxidation states, lacking partially filled d orbitals. Therefore, they do not display the typical behavior of transition metals. While Cn theoretically fits the electronic configuration, its properties are not well-studied due to its synthetic and highly unstable nature.
The d orbitals of transition elements distinguish themselves by protruding to the periphery of an atom more than other orbitals (s and p). This characteristic makes d orbitals more influenced by their surroundings. The partially filled or empty d orbitals in transition elements contribute to their uRead more
The d orbitals of transition elements distinguish themselves by protruding to the periphery of an atom more than other orbitals (s and p). This characteristic makes d orbitals more influenced by their surroundings. The partially filled or empty d orbitals in transition elements contribute to their unique properties. These orbitals play a crucial role in bonding, leading to the formation of a variety of oxidation states, colored ions, and complex compounds with ligands. The presence of d orbitals in transition elements influences their catalytic properties and paramagnetic behavior, setting them apart from non-transition elements and contributing to their diverse and versatile chemistry.
Ions with partly filled d orbitals among transition elements exhibit characteristic properties due to the ability of these orbitals to undergo electron rearrangement. The presence of partially filled d orbitals allows for multiple oxidation states as electrons can be easily gained or lost. The transRead more
Ions with partly filled d orbitals among transition elements exhibit characteristic properties due to the ability of these orbitals to undergo electron rearrangement. The presence of partially filled d orbitals allows for multiple oxidation states as electrons can be easily gained or lost. The transition metal ions absorb and emit specific wavelengths of light, leading to colored ions. Additionally, the partially filled d orbitals enable the formation of complex compounds with ligands, where molecules or ions coordinate with the central metal ion. These unique properties arise from the flexibility of d orbitals to accommodate different electron configurations, contributing to the diverse chemistry of transition elements.
