The trend of increasing second and third ionization enthalpy experiences breaks for the formation of Mn²⁺ and Fe³⁺ in the 3d series because both ions have d⁵ configurations. At d⁵ configuration, there is no loss of exchange energy, which increases the stability of the electronic configuration. The absence of loss in exchange energy results in a lower ionization enthalpy for Mn²⁺ compared to Cr⁺ and Fe³⁺ compared to Mn²⁺. These breaks are significant as they deviate from the expected trend based on the increase in effective nuclear charge, emphasizing the unique electronic configurations’ influence on ionization enthalpies in the 3d series.

The variation in ionization enthalpy for an electronic configuration dⁿ is influenced by the attraction of each electron towards the nucleus, repulsion between electrons, and exchange energy. Exchange energy plays a crucial role in stabilizing energy states and is approximately proportional to the total number of possible pairs of parallel spins in degenerate orbitals. According to Hund’s rule, the lowest energy state corresponds to the maximum extent of single occupation of orbitals with parallel spins, minimizing loss of exchange energy and increasing stability. As stability increases, ionization becomes more difficult, affecting the trend in ionization enthalpy for dⁿ configurations.

Consuming small quantities of dilute ethanol may cause mild effects like relaxation and lowered inhibitions, leading to drunkenness. In contrast, even a small amount of pure ethanol (absolute alcohol) can be lethal due to its higher potency. Long-term alcohol consumption is associated with health problems such as liver damage, cardiovascular issues, impaired cognitive function, and an increased risk of addiction. Chronic alcohol use contributes to conditions like liver cirrhosis and may lead to social and psychological issues. The cumulative impact on various organs underscores the importance of moderation and awareness regarding the potential health risks associated with prolonged alcohol consumption.
