The structure of IF 7 is as follows: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/44623482ef99307ae8fe02c8e0bd131c-.png" /> There is no lone pair of electrons on central I atom. However, each of seven F atoms contains 3 lone pairs of electrons. Hence, total number of lone pairs of electrons in an IF 7 molecule is 21 .

Q. The total number of lone pairs of electrons in an $I F_{7}$ molecule is_____.

The structure of $I F_{7}$ is as follows:

There is no lone pair of electrons on central $I$ atom.
However, each of seven $F$ atoms contains $3$ lone pairs of electrons.
Hence, total number of lone pairs of electrons in an $I F_{7}$ molecule is $21$ .
