Question

Which is the largest bond angle?

(A) angle O-S-O in SO4 2-

(B) angle CI-C-CI in HCCI3

(C) angle F-Be-F in BeF2

(D) angle H-O-H in H2O

Could you explain which answer you got and explain why?

Answer 1

To correct a mistake I made, H2O has a distorted tetrahedral geometry not Trigonal planar. The reason is that there are two lone pairs of electrons and not one. The tetrahedral bond angle is 109.5 while trig planar is 120.
