Question

what is CF2Br2 structural formula? and what is the Geometry name? is it a polar or non polar

Answer 1

Answer:

CH2F2 is polar.

The central atom is Carbon. It has 4 atoms bonded to it; thus, it has a steric number of 4.

A steric number of 4 (with 0 lone pairs) means that, according to VSEPR theory, CH2F2 has a tetrahedral geometry.

H and C both have Electronegativity values so close (on the Pauling Scale) that they are generally considered to not produce any net dipole. Fluorine however, has an extremely high electronegativity and there will thus be a negative dipole on the Fluorine.

As both Fluorines are 109.5 degrees (approximate [according to VSEPR bond angle theory]), there will be a net negative dipole pointing between the two Fluorines, making CH2F2 polar.

Answer 2

The structural formula of $CBr_{2} F_{2}$. The geometry name  is Dibromodifluoromethane. $CBr_{2} F_{2}$  is polar.

• The structural formula is $CBr_{2} F_{2}$ and the geometrical name is dibromofluoromethane.

• The molecule is polar or non-polar can be determined with the help of the arrangement of outer atoms. Carbon is the central atom in $CBr_{2} F_{2}$.
• Carbon has 4 atoms, two of which are bonded to 2 atoms of fluorine and two atoms of boron. Thus, carbon consist of 4 as its steric number.
• According to the VSEPR theory, a steric number of 4 along with zero lone pairs has a tetrahedral geometry.
• The electronegative value of fluorine is very high and boron has also high electronegativity as compared to that of carbon and as the dipole moments do not cancel out each other.
• So, $CBr_{2} F_{2}$ has a non-zero net dipole moment and hence, it is polar.  

Hence, $CBr_{2} F_{2}$ is polar molecule.
