What are the key elements in the 13th group of the P-block for NEET 2026?

The 13th group of the P-block, also known as the Boron group, primarily includes Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl). For NEET 2026 chemistry, your focus should be on the properties and reactions of Boron and Aluminum, as they are most frequently tested.

Why are P-block elements important for NEET 2026?

P-block elements constitute a significant portion of the NEET chemistry syllabus, particularly in inorganic chemistry. Understanding their trends, properties, and reactions is vital for scoring well in NEET 2026. Questions often involve their compounds, oxidation states, and unique characteristics.

What kind of reactions are typically asked about Boron compounds in NEET?

NEET exams often feature questions on the reactions of Boron with non-metals, the properties of boric acid (H3BO3), the structure and reactions of boranes (like diborane, B2H6), and the formation of boron nitride. Our MCQs provide practice for these areas.

How does Aluminum Chloride ({AlCl}_3) behave differently in aqueous medium and as a dimer?

In the solid state and gaseous phase at lower temperatures, {AlCl}_3 exists as a dimer, {Al}_2{Cl}_6. However, when dissolved in water, it hydrolyzes to form complex ions, predominantly tetrahedral [{Al(H2O)6}]3+ or octahedral species, and exhibits acidic properties due to the release of H+ ions.

What is the role of {O}_2 and {H}_2{O} in reactions with Diborane ({B}_2{H}_6)?

Diborane ({B}_2{H}_6) reacts vigorously with oxygen ({O}_2) to produce boric oxide ({B}_2{O}_3) and water. Independently, it reacts with water ({H}_2{O}) to form boric acid ({H}_3{BO}_3) and hydrogen gas ({H}_2).

Can I expect hard-level questions on 13th group elements for NEET 2026?

Yes, the NEET 2026 exam can include challenging questions on topics like the 13th group elements to test a deeper understanding. This MCQ set is designed to help you prepare for such difficult questions, focusing on specific reactions and structures.

What are the applications of Boron Nitride (BN)?

Boron Nitride exists in various forms. Hexagonal Boron Nitride (h-BN), similar to graphite, is used as a lubricant and in high-temperature applications. Cubic Boron Nitride (c-BN), structurally similar to diamond, is extremely hard and used as an abrasive. Questions on its formation from Boron and Ammonia can appear in NEET.
