(a) Interpretation: The species that is smaller between the pair given is to be predicted. Concept Introduction: Compounds formed up of ions are known as Ionic compounds. The compound consists of the cation and anion. Cation is the positively charged ion and anion is negatively charged ion. Cations are always smaller than the atoms from which they are formed because they have less number of electrons than the parent atom due to which the force of attraction between protons and electrons increases and due to this, size decreases. Anions are always larger than the atoms from which they are formed because they have more number of electrons than the parent atom due to which the repulsion between the electron increases and the force of attraction between protons and electrons decreases and due to this, size increases.

Question

Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why. CH3 Br2, light CBR3 ok-ok Br Br Br Br CI "Bromo-DDT" CCl 3 DDT (dichlorodiphenyltrichloroethane) CI
