About this paper
This is the Jharkhand Academic Council (JAC) Class 12 Chemistry paper from the 2017 board examination, with answers under the questions. It has 34 questions, from eight multiple-choice items and seven very short answers through short answers to three long answers. One numerical asks for the side of the unit cell and the number of unit cells in 1.00 cm³ of aluminium, which crystallises in a cubic close-packed structure with a metallic radius of 125 pm. Another asks how the emf of a Zn–Cu cell changes if the anode-compartment concentration is increased. The long answers give reasons about SiF₆²⁻, H₃PO₃ and PbO₂, and ask for structures including IF₇, XeOF₄ and H₃PO₄. Or alternatives cover a first-order half-life and the Arrhenius equation. Marks and time are not printed.
