- Draw the Lewis structure of acetic acid, CH3CO2H, clearly indicating all non-bonding pairs of electrons. Even though nitrogen and phosphorus have the same number of valence electrons, nitrogen can only bond to chlorine four times forming NCl4+ but phosphorus can bond with chlorine five times forming PCl5. Explain. Draw all the isomers of C4H9Br, using bond-line formulas. Draw the Lewis structure of the nitrite ion, NO2–, clearly indicating resonance contributors as well as non-bonding pairs of electrons and formal charges, as relevant. Nitromethane is a polar molecule but contains 2 equal polar covalent bonds. Briefly explain why and draw a relevant 3-dimensional structure to show the overall dipole moment of the molecule. Draw all isomers of C6H12O that are aldehydes.arrow_forwardWhat is the nature of the bonding in C3H2F2 , Is it polar?arrow_forwardChlorocyclopentadiene does not ionize easily in solution. It will ionize only when treated with a very strong Lewis acid such as antimony pentafluoride (SBF3). The product was found by electron paramagnetic resonance (epr) studies to have two unpaired electrons. Draw the structure formed when this molecule ionizes. Include all lone pairs in your structure. Ignore inorganic byproducts. H20, SbFsarrow_forward
- A particular allotrope of nitrogen, N4, was first detected in 2002. (Allotrope just means a chemical form in which an element can exist. Oxygen, for example, has two allotropes on earth: O2 and O3.) The all-nitrogen compound only lasts a short while before breaking down to N2. The compound cannot be isolated, so its structure is not yet confirmed experimentally; we can only hypothesize what its bonding and shape are. This allotrope is generally believed to be either a single ring of four nitrogens or a single chain of four nitrogens. 1. Draw the Lewis structure for both the linear form and the single ring form.arrow_forwardA particular allotrope of nitrogen, N4, was first detected in 2002.
