What word or two-word phrase best describes the shape of the fluoroform molecule?
Vlad [161]

Answer : The shape of the fluoroform molecule is Tetrahedral.

Explanation :

First we have to calculate the Hybridization of the molecule by formula,

\text{Number of electrons} = \frac{1}{2}[V+H-C+A]

where,

V = Number of valence shell electron in central atom

H = Number of neighboring monovalent atom

C = charge of cation

A = charge of anion

The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.

The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.

There is no charge of cation and anion on the given molecule.

V = 4

H = 1 Hydrogen atom + 3 fluorine atom = 4

C = 0

A = 0

By the above hybridization formula, we get

\text{Number of electrons}= \frac{1}{2}[4+4-0+0] = 4

The number of electron pair = 4

The number of lone pair = 0

The number of electrons is 4, this means that the hybridization is sp^{3} and the geometry of the molecule is Tetrahedral.

The geometry of the molecule is shown below.

Who do you think is most right?
Sati [7]

Explanation:

Bella is right

Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
