Which one of the following compounds is expected to be polar based on the molecular geometry and explain your answer.
A.) CF4
B) trans-CH2CL2
C) c2h4
D) nf3

Solutions

Expert Solution

a]

CF4 ----> Hybridisation is sp3

sp3 --> tetrahedral

In tetrahedral dipole moment is zero

b]

H.............Cl...
.....\........./.......
......C.=.C.........
..../..........\.......
Cl..............H...

If you draw a line through the chlorines, you'll see that it goes right through the center of this molecule. There's not going to be any NET polarity on this guy at all .

c]

C2H4 ---> It is a sp2 hybrisation because of double bond carbons

SHape of the molecule is trigonal planar

IN trigonal planar the net dipole moment is zero

d]

NF3

Hybridisation is sp3

Pyrimidal shape

LOne present on the Nitrogen

There will be a net dipole moment due to the presence of lone pair on the Nitrogen

Which of the following statements are true for molecular geometry? Mark ALL that apply. •Molecular geometry and electron geometry are always the same for any given molecule. •The molecular geometry describes the geometric arrangement of the actual atoms in a molecule. •There are more possible molecular geometries than there are electron geometries. •The molecular geometry can be determined without looking at the lone pairs on the central atom.
