Here are the answers to the MCQs and the short question: 1- The recommended name for ammonia by IUPAC: B) azane 2- PAN formation starts when NO_2 reacts with the hydrocarbon. B) NO_2 3- The oxidation state of 'S' in SCl_2 is: Step 1: Assign oxidation state of Cl as -1. Step 2: Let the oxidation state of S be x. x + 2(-1) = 0 x - 2 = 0 x = +2 B) +2 4- The shape of ammonium is: C) tetrahedral 5- The most stable specie in an acidic environment is: A) SO_4^2- 6- In a catalytic converter, the conversion of nitrogen oxides (NO_x) into nitrogen gas (N_2) and oxygen gas (O_2) is a process of: B) Reduction 7- Sulfur is a member of group 16 which is also called as: C) Chalcogens 8- A reddish brown gas, paramagnetic and react with water to form HNO_3 and HNO_2: C) NO_2 9- Sulfur displays a range of oxidation states principally from: C) -2 to +6 SHORT QUESTIONS 1. Why is ammonia weak base? Ammonia (NH_3) is a weak base because it only partially ionizes in water. It accepts a proton from water to form ammonium ions (NH_4^+) and hydroxide ions (OH^-), but the equilibrium lies predominantly towards the reactants, meaning only a small concentration of hydroxide ions is produced.
