Question

H-O-H Bond angle in H2O is 104.5o while F-O-F bond angle OF2 is 102o ko

.​

Answer 1

explain the standard unit of atomic mass is

Answer 2

The reason is given below

• Both the molecules i.e. H2O and F2O have bond pair and lone pair of electrons.
• The difference between the two molecules is presence of highly electronegative element fluorine in F2O, which is replaced by hydrogen in H2O.
• Thus the bond pair electrons are attracted towards fluorine in F2O while repelled towards oxygen in H2O.
• This makes the bond angle smaller in F2O in comparison to H2O.
