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]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5BV%2BH-C%2BA%5D)
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
= 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
and the geometry of the molecule is Tetrahedral.
The geometry of the molecule is shown below.
Answer : The O-O bond in
will be longer than the O-O bond in
.
Explanation :
In the
, the two oxygen atoms are bonded by the single bond and in
, the two oxygen atoms are bonded by the double bond.
As we know, the bond strength of double bond is greater than the single bond.
And the relation between the bond strength and bond length is,

That means the higher the strength, the shorter will be the bond length.
Hence, the bond length of single bond will be longer than the double bond.
The structure of given molecule is shown below.
Answer:
The reaction in this experiment is termed an iodine clock reaction, because it is the molecular iodine (I2) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with the starch in the solution to form a complex, turning it a deep blue-black color.
I would it true because they do alot of experimenting
