Structural Formulas and Partial Charges in Ammonia (NH3) and Carbon Dioxide (CO2)

The structural formulas and partial charges in ammonia (NH3) and carbon dioxide (CO2) are as follows:

1. Ammonia (NH3): - Structural Formula: H-N-H - In ammonia, the central nitrogen atom (N) is bonded to three hydrogen atoms (H) through single covalent bonds. - The nitrogen atom has a partial negative charge (δ-) due to its higher electronegativity compared to hydrogen. - The hydrogen atoms have partial positive charges (δ+) due to the electron density being pulled towards the nitrogen atom.

2. Carbon Dioxide (CO2): - Structural Formula: O=C=O - In carbon dioxide, the central carbon atom (C) is double-bonded to two oxygen atoms (O) through two double covalent bonds. - Both oxygen atoms have partial negative charges (δ-) due to their higher electronegativity compared to carbon. - The carbon atom has no partial charge (neutral) as the electron density is evenly distributed between the two oxygen atoms.

Please note that the partial charges mentioned above are relative and represent the distribution of electron density in the molecules.
