Question

Complete the following table with required information (this is similar to lab on geometries of molecules and ions) Total Lewis structure Shape Overall polarity # valence e—
a. S2F2
b. N2H2
c. C2N2

Answer 1

Steps to draw a lewis structure
1)Find the total number of valence electrons from the periodic table
2) Put the least electronegative element in the center
3) put two electrons between atoms to form a chemical bond
4) complete octet on the outside atoms
5) if centre atom does not have an octet move electrons from outer atoms to form double bonds and triple bonds
