1.	An isotope of hydrogen (A) reacts with diatomic molecule of element which occupies group number 16 and period number 2 to give compound (B) is used as a modulator in nuclear reaction. (A) adds on to a compound (C), which has the molecular formula C3H6 to give (D). Identify A, B, C and D.
Answer» Solution :(i) An isotope of hydrogen Deuterium (A) reacts with diatomic MOLECULE of element belongs to group number 16 and PERIOD number 2 oxygen O, to give a COMPOUND (B) which is heavy water `D_(2)O.D_(2)O` is USED as a moderator in nuclear reaction. `underset("Deuterium"(A))(2D_(2))+O_(2)tounderset( Heavy water (B))(2D_(2)O` (ii) Deuterium reacts with `C_(3)H_(6)` propane (C) to give Deutero propane `C_(6)D_(6).(D)` `3d_(2)+underset("Propane")(C_(3)H_(6)tounderset( "Deutero propane")(C_(3)D_(6)+3H_(2))`
