Shapes of molecules

?
Which of these molecules has a linear shape? -BF3 -CO2 -SO2
CO2
1 of 5
How many bond pairs and lone pairs are present in SiCl4, and what is its shape?
4 bond pairs and 0 lone pairs are present, therefore it has a tetrehedral shape.
2 of 5
Why does PH4+ have a greater bond angle than PH3?
PH3 has one lone pair of electrons. PH4+ has no lone pairs. Lone pairs repel more than bond pairs, therefore the bond angle in the molecule with a lone pair will be smaller, as the pairs are pushed closer together.
3 of 5
What is the shape and bonding angle in PF6-?
It has an octahedral shape and a bonding angle of 90 degrees.
4 of 5
What is the shape and bonding angles present in NH3?
It has a pyramidal shape as it has 3 bond pairs and 1 lone pair, therefore it has bond angles of 107 degrees.
