QUESTION 5 Cоmpоunds cоntаining different hаlogen аtoms covalently bonded together are called interhalogen compounds. 5.1 One interhalogen compound can be prepared by the reaction between iodine and fluorine. This compound has Mr = 222 and the percentage composition by mass is: F, 42.8; I, 57.2. Calculate the molecular formula of this interhalogen compound. [3] 5.2 Another interhalogen compound has the formula ICl. Draw a ‘dot-and-cross’ diagram of a molecule of this compound, showing outer shell electrons only. Explain whether or not you would expect this molecule to be polar. [2] [5]
