Answer: Option (b) is the correct answer.

Explanation:

More is the electronegativity of an atom or element more will be its reactivity.

When we move across a period from left to right in a Periodic table then there will increase in electronegativity. And, when we move down a group then there will be decrease in electronegativity.

Oxygen, sulfur and selenium are all group 16 elements. So, their electronegativity decreases down the group. Also, nitrogen is less electronegative than oxygen atom.

Hence, we can conclude that out of the given options element oxygen is more reactive than the others.

The electronegativity of C = 2.5, O = 3.5. What type of bond is between C-O? ______ ______ bond
Schach [20]

Answer:

Polar covalent bond

Explanation:

On the basis of electronegativity bond could be ionic bond, polar and non pole covalent bond.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.  The electronegativity difference between bonded atoms is greater than 1.7.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.  There are two type of covalent bond. Polar and non polar covalent bond. When electronegativity difference is 0.4 - 1.7 bond is polar covalent bond when it is less than 0.4 the bond is non polar covalent.

For example:

In CO the electronegativity of oxygen is 3.5 and carbon is 2.5. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and carbon becomes partial positive. and bond is polar covalent.
