NEET Pattern Practice Questions

Stop Revising. Start Scoring.

Sections 1 to 15 taught you the chapter. This section finds out whether you can use it at NEET speed, which is a completely different skill from understanding it. There is no new theory here — just 30 questions built to the NEET pattern (single-correct MCQs, plus the assertion-reason, match-the-column and statement-type formats NEET now uses freely), and a marking scheme that punishes the one thing students do most on this chapter: picking a shape, a bond order or a dipole they half remember.

The rules of engagement

Key Point: Do not treat this as a reading exercise. Sit down with a blank sheet, a pen and a timer, and attempt all 30 questions in one unbroken sitting before you look at a single explanation.

[NEET] One minute per question is not a suggestion; it is the whole game. Chemical Bonding is the chapter NEET samples most heavily from Class 11 Chemistry, and almost every question in it is a "recognise and apply" question: count the electron pairs, name the shape, write the MO configuration, read off the bond order. A well-prepared student needs 30 to 50 seconds per question. If one is eating two minutes, you are re-deriving something (the MO energy order, the VSEPR shape table) that you should simply know by now. Mark it, move on, come back; that is exactly what you will have to do in the hall.

NEET's guessing maths

That $-1$ is not decoration. Do the arithmetic once and you will never guess blindly again:

[Board] The rule that comes out of that table: narrow first, then commit. Every question below has at least one option that is a "trap" built from a common mistake — $\mathrm{NF_3}$ given a larger dipole moment than $\mathrm{NH_3}$ because fluorine is "more electronegative", $\mathrm{XeF_4}$ called tetrahedral because it has four bonds, $\mathrm{O_2^-}$ given a higher bond order than $\mathrm{O_2^+}$ because it has "more electrons", HF placed at the bottom of the hydrogen-halide boiling-point order. Learning to see the trap is what turns a blind guess into a two-option choice, and $+0.25$ into $+1.5$.

What this set covers

That spread is deliberate — it mirrors how NEET actually samples this chapter. Shapes, angles and hybridisation (6 questions) and molecular orbital theory (5 questions) together make up more than a third of the set, because in the real paper they are where this chapter earns most of its marks; Lewis structures and formal charge are the next biggest block. Woven through the set are four assertion-reason questions, two match-the-column questions and two "which statement is correct/incorrect" questions, because NEET uses all three formats and each has its own way of tricking a student who reads too fast.

[NEET] For assertion-reason questions, decide the truth of A and R separately before you even think about whether R explains A. Most wrong answers on this format come from students who judged the pair as a whole — and in this chapter NEET loves a Reason that is true but about the wrong thing (a true statement about electronegativity offered as the explanation for a dipole-moment fact that actually depends on the lone pair, for instance).

Scoring Yourself Honestly

Mark your sheet with the real scheme — $+4$, $-1$, $0$ — and total it. Do not award yourself half marks for "I knew that one really". The number you get is the number that matters. And note the time you actually took: a 110 in 45 minutes and a 110 in 30 minutes are very different results in a NEET context.

The bands

Read your own answer sheet: the three error piles

Before you touch the explanations, sort your mistakes into three piles. This is the most valuable ten minutes in the whole section.

1. Concept errors — you did not know that formal charge is a bookkeeping number and not a real charge, that lattice enthalpy rises with ionic charge far more than with anything else, that a lone pair repels harder than a bond pair, that the $\pi 2p$ orbitals sit below $\sigma 2p_z$ for $\mathrm{B_2}$, $\mathrm{C_2}$ and $\mathrm{N_2}$ but above it for $\mathrm{O_2}$ and $\mathrm{F_2}$, or that HF boils below water even though its hydrogen bond is stronger. Fixable by revision, and quickly: the topic map tells you exactly which section to reopen.
2. Execution errors — right idea, wrong arithmetic; you counted 7 sigma bonds as 8 because you counted the triple bond's sigma twice; you wrote 16 electrons for $\mathrm{O_2^-}$ instead of 17; you added the two charges of $\mathrm{CO_3^{2-}}$ to the electron count with the wrong sign; you gave $\mathrm{SF_4}$ five bond pairs. Fixable by slowing down for four seconds and writing the count instead of doing it in your head.
3. Reading errors — the question asked for the incorrect statement and you picked a correct one; it asked for bond length order and you gave bond order; it asked which species is diamagnetic and you picked the paramagnetic one; it asked for the shape of $\mathrm{XeF_4}$ and you gave the electron-pair geometry. These are the cheapest marks in the paper to win back, and the ones students refuse to take seriously.

Key Point: A student who scores 84 with three concept errors is in far better shape than one who scores 84 with nine reading errors. The first has three things to learn. The second has a habit to break, and habits take longer.

[NEET] In NEET, the assertion-reason, match-the-column and statement-type questions are where reading errors pile up. If two or more of your mistakes are on Q3, Q4, Q5, Q9, Q12, Q16, Q18 or Q26, that is a format problem, not a chemistry problem — practise the format.

[Board] Every explanation below is written as a full step-by-step solution, so this set doubles as revision material. Read the explanation even for the questions you got right — sometimes you got there the slow way, and the fast way is what you will need in the exam hall.
