My teacher gave me a table of all the names of the molecules possible, bond angle that they had, an example of one, the number of lone pairs, and the number of lone pairs.

Im wondering if someone could do me a huge favour and remake this table for me, because ive lost the one which i was given.

This isn't great but it may help....

Linear - 180
Bent - 108
Trigonal Planar - 120
Pyramidal - 108
Tetrahedral - 109

And this site here may be useful to.

I was taught:

linear - 180 (duh)
tetrahedral - 109.5
pyramidal with a lone pair - 107
v-shaped with 2 lone pairs - 104.5

(note that the lone pairs are generally more negative than a covelant bond so they cause more repulsions between themselves and therefore less between the actual covelant bonds due to lack of space)

trigonal planar - 120 (360/3 obvious)
trigonal bypiramid - 90 between the triangle plane and the line perpendicular to it(going through it), and 120 between bonds on the trigonal plane

And the last one, which I've forgotten the name if which has 6 (cubic possible) has all angles of 90

If you are doing edexcel AS chemistry then this site is great. But if ur not then it has all the bond angles
