- Use the following Lewis diagram for 1-propanol to answer the questions: H H H H- 2 Remember that geometry refers to the geometry defined by the atoms, not the electron pairs. The geometry about atom Cq is linear The ideal value of the C-C-C angle at atom C2 is 115 degrees. The geometry about atom O3 is triangular planararrow_forwardH H- Br -H •S: Consider the Lewis structure provided above. Answer the following questions about the compound in the provided boxes. (A) What is the class formula (AXE₂)? Note that you do not need to use subscripts. type your answer... (B) What is the steric number? type your answer... (C) What is the electron geometry? type your answer... (D) What is the molecular geometry? type your answer... (E) What is the hybridization of the central atom? Note that you do not need to use superscripts type your answer...arrow_forwardDetermine the number of rigid (TT) bonds in the molecule pictured.arrow_forward
- You are given part of a molecule shown below. Assume that the two atoms are covalently bound to each other and to a larger molecule at the first dash symbol. Can the atom that is underlined (as shown) participate in a hydrogen bond with another atom from a different molecule? −O−H −C−H −N−H −O−H −C−H Can the oxygen of -O-H participate in a hydrogen bond? Can the hydrogen of -C-H participate in a hydrogen bond? Can the nitrogen of -N-H participate in a hydrogen bond? Can the hydrogen of O-H participate in a hydrogen bond? Can the carbon of -C-H participate in a hydrogen bond?arrow_forwardExplain the difference between a polar bond and a polar molecule.arrow_forwardWhich viewing mode(s) (ball & stick, ball & bond type, tube or wireframe) gives the most information about a molecule's structure and why?arrow_forward
- Why do polar molecules have a greater tendency to remain a liquid or a solid at room temperature?arrow_forwardUse the VSEPR model to predict the bond angles around each central atom in the following Lewis structures (benzene rings are frequently pictured as hexagons, without the letter for the carbon atom at each vertex). Note that the drawings do not necessarily depict the bond angles correctly.arrow_forwardIf a drop of oleic acid is added to a dish of water, the oleic acid will spread out and form a layer that is one molecule thick on top of the water. (a) Draw the Lewis structure for oleic acid. (b) Label the region of the oleic acid molecule that is polar and the region that is nonpolar. (c) In the layer of oleic acid that forms, which part of the oleic acid molecule points down into the water and which part points out of the water?arrow_forward
