Iodine conducts electricity due to self-ionization, reaction of which is mentioned below- 3퐼2 ⇌퐼3 + + 퐼3 − P-BLOCK ELEMENTS (GROUP 15-18) 16 Also, the conductivity will increase with increase in temperature and it behaves like the semiconductor. Here, all the options given are correct. Thus, the correct option is (d) All of above 100. Which of the following is arranged in order of increasing bond energy? (a) I2< Br2< Cl2< F2 (b) I2< F2< Br2< Cl2 (c) I2< Br2< F2< Cl2 (d) Cl2< Br2< F2 < I2 2 2 2 2 Cl >Br >F >I exceptional Due to high e– repulsion between non-bonding e–. In 2p – orbitals of flu
