What is the nature of the se-cl bond in a molecule of selenium chloride (secl2) if the electronegativity value of selenium is 2.55 and that of chlorine is 3.16? nonpolar covalent moderately polar covalent highly polar covalent ionic polar ionic

moderately polar covalent

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of 0.4 to 2 in electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms.  An electronegative atom is the one which attracts the shared pair of electron towards itself.

Non-polar covalent bond is defined as the bond which is formed when there is less than 0.4 difference in electronegativities between the atoms.

Ionic bond is formed when there is complete transfer of electron from one atom to another atom which is formed when there is more than 2.0 difference in electronegativities between the atoms.

The given electronegativities of chlorine is 3.16 and that of seleium is 2.55, hence the difference is (3.16-2.55) = 0.61 , which is less than 1.7 and thus bond is moderately polar covalent.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it's all four options.
