Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent?

(a) s8
(b) rbcl
(c) pf3
(d) scl2
(e) f2(f) sf2

Answers :

Solution of each part is given below.

Explanation:

a)     non polar covalent  ( because each sulphur atom shares electron and the net dipole moment is zero.)

b) RbCl    ionic  ( Rb have good tendency to donate electron and chlorine is too electro negative therefore they make strong ionic bond.)

c)   polar covalent ( because of triagonal pyramidal geometry and strong electronegativity of F atom it is polar and covalency is due to the share of electron with each F atom.)

d)  polar covalent ( because of tetrahedral geometry and sharing of electrons between S and Cl.)

e)   non polar covalent ( because of linear geometry they are non polar and bond between them is formed due to sharing electrons.)

f)   polar covalent ( because of T- shape geometry they are non polar and due to sharing of electrons they are polar covalent.)

Hence, this is the required solution.
