Answer #1

S-S Bond:

S is a non metal. Generally bond between two non metals is covalent. And also here both the elements are same. So equal sharing takes place between the atoms. Hence S-S Bond is non polar.

O-H bond:

This a covalent bond.(both are non metals) But there is an electronegative difference between O and H. So it is a polar covalent bond.

Ca-Cl bond:

Here the bond is between metal and nonmetal. In this complete transfer of electrons takes place. So Ca-Cl bond is ionic

The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is canceled by the symmetric tetrahedral shape. When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes polar. Use Figure 9.20 to rank the following molecules from the least polar to the most polar: CH2Br2, CF2Cl2, CH2F2, CH2Cl2, CBr4, CF2Br2. (Type your answer using the format NH4 for NH4.)
