Write down the Lewis dot structures of each of the following molecules. Check the formal charge in each case and make use of it to decide on the correct structure where necessary. In cases where delocalised bonding occurs show all the resonance forms. In each case show all steps in arriving at the structure.a) CH2Cl2b) CH3CH2NH3+(here the 3 H atoms are attached to one C atom, and 2 H atoms and a Natom to the other C atom)c) CH3NNN (here 3 H atoms and 1 N are attached to the C atom and the N atoms form a 3atom chain). [Challenging: hint, share leftover electron pairs equally between the two Natoms in the middle after you have completed the octet on the end N]d) NCl3e) ClO3−(chlorate anion = chlorine bonded to 3 oxygen atoms, Hint: Cl does not obey theoctet configuration)
