Original concept-practice preview
This limited reader preview contains newly authored practice items, not original NTA question paper text. A separate working manuscript contains 12 such problems across GOC, Thermodynamics and Equilibrium; independent academic QA is still open.
1 · Organic Chemistry
In CH₂=C(CH₃)₂, how many hydrogen atoms are present on the two methyl groups adjacent to the double-bond carbon?
Reveal reasoning
Two methyl groups × three hydrogen atoms each = six. The alkene CH₂ hydrogens do not belong to the adjacent methyl groups.
2 · Thermodynamics
For an ideal-gas reaction with Δn(gas)=+2 mol per mole of reaction, what is ΔH−ΔU?
Reveal reasoning
Under ideal-gas conditions, ΔH−ΔU=Δn(gas)RT=2RT. Match the units of R to the desired energy units.
3 · Equilibrium
At fixed temperature, K=10 and Q=2. In which direction does net reaction progress?
Reveal reasoning
Q is less than K, so the forward direction is favoured to approach equilibrium, assuming the reaction can proceed. This alone gives no kinetic rate.
4 · Study method
Why should an incorrect PYQ-style answer produce a prerequisite task rather than just a correct-answer display?
Reveal method
The error could reflect an underlying gap in concepts, representation, units or application. Diagnosis should select a targeted explanation, an isomorphic question and a delayed recall test before declaring improved mastery.
