P-Block - NEET Previous Year Questions with Complete Solutions

Yes, NCERT Class 12 Chemistry Chapters 7 and 8 cover approximately 85–90% of what NTA asks in P Block. However, NCERT must be read deeply — every reaction, every structure diagram, and every exception mentioned in the text or in-text boxes is fair game. Pair NCERT reading with solved PYQs to cover the remaining 10–15%.

The highest-priority P Block topics for NEET are: structures and basicity of oxoacids of phosphorus and sulphur, hybridisation and geometry of xenon fluorides (XeF₂, XeF₄, XeF₆), interhalogen compounds, allotropes of carbon and sulphur, and the anomalous behaviour of the first member in each group. These topics have appeared in at least 4 of the last 6 NEET papers.

NTA typically asks 3 to 5 questions from P Block Elements in NEET Chemistry each year, contributing 12–20 marks. Based on papers from 2019 to 2024, Group 15 (nitrogen family) and Group 16 (oxygen/sulphur family) appear most frequently, followed by xenon compounds from Group 18.

Per the NTA NEET syllabus, P Block is covered across two chapters: P Block Elements (Part 1) in Class 11 covers Groups 13 and 14, while P Block Elements (Part 2) in Class 12 covers Groups 15, 16, 17, and 18. NEET questions come from both parts, with Part 2 (Class 12) typically contributing more questions.

Draw each structure by hand — do not rely on recognition alone. For oxoacids, use the rule: count P–OH bonds for basicity and check if the central atom has a P=O bond to determine reducing nature. For xenon compounds, count bonding pairs + lone pairs around Xe to determine hybridisation and geometry quickly.

Solving 5–6 years of P Block PYQs is extremely effective but not entirely sufficient on its own. PYQs build pattern recognition and reveal NTA's preferred question styles. Combine them with thorough NCERT reading, structure drawing practice, and at least one mock test under exam conditions. Students in eSaral's NEET batches — guided by IIT Bombay faculty — follow this exact sequence.
