The molecular geometry of the chf3 molecule is and the molecule is a. trigonal pyramidal, polar b. tetrahedral, nonpolar c. tetrahedral, polar d. seesaw, polar e. seesaw, nonpolar

The correct option is: C. tetrahedral, polar

Explanation:

Trifluoromethane, also known as Fluoroform, is a chemical compound with the molecular formula CHF₃.

Since three fluorine atoms and one hydrogen atom is bonded to the central carbon atom and there are zero lone pairs on the carbon atom. Therefore, the molecular geometry and shape of CHF₃ is tetrahedral.

As there are three carbon-fluorine polar bonds in CHF₃ molecule, thus there is a net dipole moment. Therefore, CHF₃ is a polar molecule.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.
