Question

2. How many lone pairs are assigned to the iodine atom in IF? b.1 c. 2 d. 3 a. 0 e. 4

Answer 1

Answer:

3 lone pairs

Explanation:

I and F belong to Group VIIA of the Periodic Table, so they have 7 valence electrons. In order to complete the octet, they form 1 single covalent bond. For I, as we can observe in the Lewis structure, 2 electrons are involved in that bond, while 6 electrons are not shared, forming 3 lone pairs.
