1 . If there are non - handed domains , the shape we predict might not be the
actual shape .
\The tetrahedron shape has four electron domains coming out of the center*
element . Single or double bands on the molecule can change the molecule*
geometry so that it looks like a tripod .`
The importance of having & electrons is that it makes the matecule stable*
each molecule tries to have & electrons in order to be stable .
Non - bonded electron pairs help to determine the shapes of molecules by
distorting the shape of the molecular model . For example , a model with 3
domains should have a trigonal planar shape but having a non- bonding
domain will make the shape bent .
COZ and 502 don't have the same molecular geometry because SOZ has two
more valence electrons as well as three domains , while COZ only has two
domains . COZ is linear and 502 is expected to be trigonal planar but is
Do they have
actually bent . Both 03 and 502 had one non -bonded domain out of the three .*
G. NF 3 should be tetrahedron , but actually is trigonal pyramidal . For H25 , it is
expected to be tetrahedron but is bent . CL. 20 is also expected be tetrahedron
but is bent. HZD is similar to H25 and CL. 20. NH3 was similar to NF3 .
1 . The shape that the molecule is expected to be may not be the actual shape
depending on its non- bonding domains .
2. No, atoms with an odd number of valence electrons cannot obey the octet
rule because they create free radicals . Both NO and NOZ do not obey the octet
Reflecting on the Investigation
1 . In advertising we study graphs that attempt to predict trends in consumer
behavior and purchases .
The molecules are 3 D on the computer , but you're not able to physically see
the shape or touch the molecule unless you actually make the molecule*
yourself . The molecule in the textbooks are only 2D .
A greenhouse gas is any type of gas that absorbs infrared radiation , which
then traps 8:096 ofheat in our atmosphere that the earth is trying to lose . COZ
functions as a greenhouse gas by trapping more heat on earth , which
increases the temperature . All the molecules from this experiment can act as
greenhouse gases besides N 2, 02, and 03 because those three are homo -
atomic molecules which aren't capable of being greenhouse gases .
4 . 03 absorbs harmful radiation in the stratosphere and protects us from the
sun . It is formed by 02 - 20 then 0 + 02_> 03...
