C H H C = C H H Xxx-xx H H A The diagram above shows two resonance structures for a molecule of CH. The phenomenon shown in the diagram best supports which of the following claims about the bonding in CH? B C D In the CH, molecule, all the bonds between the carbon atoms have the same length. 6 Because of variable bonding between its carbon atoms, CH, is a good conductor of electricity. 6 The bonds between carbon atoms in CH are unstable, and the compound decomposes quickly. The CH molecule contains three single bonds between carbon atoms and three double bonds between carbon atoms.

Examples: Example: H▬N▬H HIN: Examples: :F Н lone pair : -bond pair (2 e-) single bond :F: Non-Polar 8+. H :F: H:Cl: HCl:o is better represented as closer to Cl due to its greater electronegativity. Thus, HCl contains a polar covalent bond. H :0: Polar lone pair 8- :S H -S= :0: 2 bond pairs (4 e-) double bond because the bond electrons are pulled F: Pola

Decide whether the Lewis structure proposed for each molecule is reasonable or not. Note: If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. For example, if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice.
