The number of ions produced from one molecule of \(\left[\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{Br}\right] \mathrm{Br}_{3}\) in the aqueous solution will be (a) 4 (b) 5 (c) 6 (d) 7

Coordination chemistry is a branch of inorganic chemistry that deals with the study of coordination compounds. These are complex molecules where a central metal atom is surrounded by molecules or ions known as ligands. The ligands are bonded to the metal atom through coordinate covalent bonds, also known as dative bonds, where both electrons are donated by the ligand.

In a coordination complex, such as \(\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_5 \mathrm{Br}\right] \mathrm{Br}_3\), the platinum (\(\mathrm{Pt}\)) serves as the central metal, while ammonia (\(\mathrm{NH}_3\)) and bromine (\(\mathrm{Br}\)) act as ligands. Understanding this structure is vital because the geometry and bonding of the coordination complex can influence properties such as color, magnetism, and reactivity. These are typical exam topics for NEET chemistry preparation.

Ionic compounds consist of positive and negative ions held together by strong electrostatic forces known as ionic bonds. In the case of the given complex \(\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_5 \mathrm{Br}\right] \mathrm{Br}_3\), ion-dissociation in an aqueous solution involves breaking the ionic bonds between the complex cation and the anionic bromides.

During dissolution, the complex ion \(\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_5 \mathrm{Br}\right]^{2+}\) remains together, forming a single entity, while the three bromide ions (\(\mathrm{Br}^-\)) separate completely. Ion-dissociation in this context highlights the discrete nature of ionic compounds in solutions, which is an important aspect of their behavior that students must understand.

Key Takeaways from Ion-Dissociation

• Analyzing the initial ionic composition is essential to predicting the possible ions in solution.
• dissociation leads to a number of ions that reflects the original stoichiometry of the compound.

Preparing for NEET Chemistry involves a deep dive into concepts like coordination chemistry and the behavior of ionic compounds. Clarity on topics such as ion-dissociation is a must for students aiming to excel in the exam.

When confronted with a problem like determining the number of ions produced from a coordination compound in the solution, NEET aspirants should approach it systematically, as shown in the step-by-step solution provided.

Efficient Study Tips

• Thoroughly understand each concept, do not just memorize solutions.
• Practice with a variety of problems to build a strong foundational knowledge.
• Regularly refer to textbooks and educational platforms for structured content and guidance.

A strong groundwork in these areas will lead to better problem-solving skills and greater confidence in handling a variety of questions on the exam.
