Question

Find the bonding type, number of balance electrons, Lewis structure, electronic shape, molecular shape, formal charges, and molecular dipole for the following molecules:

A. N2H2

B. NaCl

C. ICN^-

D. CH3(CH2)4CH3

E. PCL5

F. BaF2

Answer 1

A. N2H2 --> bonding type is covalent polar,

electronic shape --> no central atom...

molecular shape --> double bent molecule

molecular dipole --> negative in Nitrogen pole, possitive in hydrogen poles

B. NaCl

ionic bonding

electron shape --> crystal

molecular shape -> linear/crystal

formal charges --> +1 and -1

molecular dipole --> negative in Cl, positiv ein NaCl

C. ICN^-

bond type is covalent polar

electron shape/molecular shape = linear

dipoles --> negative in Nitrogen/iodine, positive in C
