Which of the following statements is correct for the iodine molecule?
A.In liquid state it conducts electricity, though very✓ Correct
B.Its conductivity increases with the rise in
C.It behaves like an intrinsic semiconductor
D.All the above
Explanation
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
