Which of the following statements is/are incorrect? 1) All the interhalogen compounds are diamagnetic in nature except ICl. 2) The diatomic interhalogen compounds give addition products on treated with olefins. 3) BrF₃ is used as brominating agent and IF₇ is used as fluorinating agent.

1) All the valence electrons in interhalogen compounds are present as bonding electron pairs (i.e. lone pairs), so these are diamagnetic in nature. 2) The diatomic interhalogen compounds undergo addition reaction through olefinic double bond sites to form addition products. 3) BrF₃ and IF₇ have been reported so far as fluorinating agents. Hence, the statements 1 and 3 both are incorrect.
