Question

explain the bond angle in F2o is smaller than that in H2o​

Answer 1

Answer:

In an A-X bond where the atom electronegativities are very different the bonding pair is assumed to occupy less space than in bond between two atoms of similar electronegativities. As the bonding pair occupies less space it will repel neighboring electron pairs less.

Both H2O and F2O have a lone pair of electrons. But fluorine being highly electronegative than hydrogen(4.0 and 2.1 respectively), the bond pair of electrons are drawn more towards F in F2O, whereas in H2O it is drawn towards O.So in F2O the bond pairs being displaced away from the central atom, has very little tendency to open up the angle. But in H2O this opening up is more as the bond pair electrons are closer to each other. So bond angle of F2O is less than H2

Explanation:

Answer 2

Fluorine is more electronegative so it attracts the lone pair of electron more towards itself which causes a decrease in its bond angle.

Explanation:

It is known that fluorine is more electronegative in nature as compared to oxygen atom. As we know that, a lone pair of electron is present on both fluorine and oxygen in $F_{2}O$ and $H_{2}O$.

Since, fluorine is more electronegative in nature so it will attract the lone pairs more towards itself due to which the bond pairs will move closer to each other leading to a decrease in bond angle of $F_{2}O$.

On the other hand, oxygen is less electronegative so it will not attract the lone pair of electrons much towards itself. Due to this there will occur not much decrease in the bond angle of $H_{2}O$.
