I believe the correct answer is B
When an atom of the element lithium (Li) transfers an electron to an atom of the element fluorine (F), then the bond results between the atoms is ionic bond.
<h3>what is chemical bond? </h3>
A chemical bond is defined as the bond which holds atoms together in molecules.
Bonds arise due to the electrostatic forces present between positively charged atomic nuclei and negatively charged electrons.
<h3>Types of chemical bond</h3>
- Ionic bond
- Covalent bond
- Coordinate bond
<h3>What is Ionic bond ? </h3>
Ionic bond is defined as the transfer of electron from one atom to another atom.
Since, electron transfer from lithium to fluroine. Thus lithium get positive charge and fluorine occupy negative charge.
Thus, the bond form between lithium atom and fluorine atom is ionic bond.

Answer:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
Overall Rate = k1[H2] [ICl]
Explanation:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
The overall reaction is the sum of the two two reactions shown in the question. After the two reactions are summed up properly, this overall reaction equation his obtained.
Since K1<<K2 it means that step 1 is slower than step 2. Recall that the rate if reaction depends on the slowest step of the reaction. Hence
Overall Rate = k1[H2] [ICl]
Here we have to choose the correct statement behind the polarity of the water molecule.
The polarity of the water molecules is due to the B. deflection of the hydrogen atoms by the lone pair of electrons.
The bonding of the water (H₂O) molecule is shown in the figure. There remain two lone pair of electrons on the oxygen atom. The oxygen atom has 6 valence electrons among which 2 are involved to make the covalent bond with two hydrogen atom.
The lone pair if electrons exerted lone pair-bond pair repulsion and H₂O has a bent structure as shown in the figure. In this way the dipole moment generated by oxygen and hydrogen cannot be nullified and it has a permanent dipole moment which leads the molecule to be polar in nature.
The water molecule is not linear in nature it has bent structure.
There is a huge difference of electronegativity between the hydrogen (H) and oxygen (O) atom. The oxygen atom is highly electronegative whereas the hydrogen atom is electropositive in nature.
The hydrogen bond formation is due to the fact the molecule is polar in nature.
The atoms which make up the ion are covalently bonded to one another. 19) It is possible for a compound<span> to possess </span>both ionic and covalent bonding<span>. a. If one of the </span>ions<span> is polyatomic then there will be </span>covalent bonding<span> within it.</span>
