The following are aresome statement about oxides of VA group element
I) `N_(2)O` molecule is linear
II) `NO_(2)` molecule is angular
III) `N_(2)O_(5)` molecule is angular
The correct combination is

Text Solution

Verified by Experts

In `BeF_(2), Be` is surrounded only by 2 electron bond pairs and therefore, the molecule is linear. On the other hand, in `SF_(2)`, the central atom S, is surrounded by 2 bond pairs and 2 lone pairs. Since it is surrounded by 4 electron pairs, the geometry is expected to be tetrahedral with two positions occupied by lone pairs.
`F-Be-F`
Because of the larger repulsions of lone pair - bond pair, the bond angle is less than `109.5^(@)` and the resultant molecule is angular.
