Question

Which molecule containes center atom that has expanded valance shell ?

I) PO₄^-3

II) PI₃

III) ICl₃

IV) OSCl₂

V) SF₄

VI) ClO₄^-1

^{These are the options :}

a. I, II og V

b. III og V

c. I og III og VI

d. IV og VI

e. II og V

Answer 1

Option C is correct due to expanded valance shell. PO4^3- , ICl3, and ClO4^-1 shows expanded octate. Hence they also shows expanded valance shell. Hence option c is correct
