Question

Asending order of bond angle? (1)ClO2 (2)H2O (3)OF2 (4)OCl2

Answer 1

The principle is that the larger the atoms on the two sides are, the wider the angle between them.
H₂O with two hydrogens and bond angle of 109.5^o
ClO₂ with two oxygen atoms and bond angle of 111^o
F₂O with two fluorine atoms and bond angle of 104.5^o
OCl₂ with two chlorine atoms and bond angle of 109.47
Hence,, the ascending order of bond angle is as follows,
F₂O < OCl₂ < H₂O < ClO₂
