Concept Introduction:
The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also known as Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.

- Determine the number of valence electrons in SiF₄ and then draw the corresponding Lewis structure.arrow_forwardThe carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]arrow_forwardConsider peroxynitrite (chemical formula: ONOO−), a structural isomer of the nitrate anion. It is generated in the cell when nitric oxide (NO) reacts with the superoxide radical anion (O2-.). Peroxynitrite is a potent oxidant and nitrating agent and can lead to DNA and protein damage (this is the complete question) Draw the correct Lewis structure for peroxynitrite and indicate approximate bond angles. Tell how many molecular degrees of freedom of motion are present in peroxynitrite and what motions they correspond to.arrow_forward
- Draw a Lewis structure for BrCl5 . What is the molecular geometry around the central atom in the Lewis structure?arrow_forwardChloral, Cl3C—CH=O, reacts with water to form the sedative and hypnotic agent chloral hydrate, Cl3C—CH(OH)2. Draw Lewis structures for these substances, and describe the change in molecular shape, if any, that occurs around each of the carbon atoms during the reaction.arrow_forward4. Draw the Lewis structure of the ozonide ion, O32−. (Assign lone pairs, radical electrons, and atomic charges where appropriate.)arrow_forward
- Write the Lewis structure for the NH4 + ion.arrow_forwardDraw the Lewis structure of Sbl3. Calculate the number of valence electronsarrow_forwardSulfur tetrafluoride reacts slowly with oxygen gas to form sulfur tetrafluoride monoxide. Write a balanced chemical equation for the reaction. In the sulfur tetrafluoride monoxide molecule the O atom and the four F atoms are bonded to a central S atom. Write a Lewis structure for this molecule in which the formal charges of all atoms is zero. Use bond energies to estimate the enthalpy of the above reaction. (S-F bond energy = 327 kJ/mole). Is it endothermic or exothermic? Determine the electron geometry of the molecule and predict two possible molecular geometries. Which of the two molecular geometries in part d is more likely to be observed? Explain.arrow_forward
- 10.) The structural formula of a certain aldehyde (related to formaldehyde) is H3C-CH2-CHO. Draw a Lewis structure for this aldehyde and determine the number of bonds present. Note that a single or a double or a triple bond counts as one bond. Write the number, not the word.arrow_forwardHow many double bonds can be found in the best Lewis stucture of COF 2?arrow_forwardChloroform, also called trichloromethane, (CHCl₃) is an important laboratory solvent with a relatively high vapor pressure at room temperature. Draw the Lewis structure of CHCl₃ and then determine the ideal bonding angle(s) for the Cl-C-Cl bond(s).arrow_forward
