- What is meant by a chemical bond? Why do atoms form bonds with each other? Why do some elements exist as molecules in nature instead of as free atoms?arrow_forwardWrite the Lewis structure for each molecule.a. CH2O b. C2Cl4arrow_forward116) Write Lewis structures and predict whether each of the following is polar or nonpolar. a. HOCN (exists as HO−CN) c. XeF2e. SeF6 b. COSd. CF2Cl2f. H2CO (C is the central atom)arrow_forward
- Write the Lewis structure for each ion. Include resonance structures if necessary and assign formal charges to all atoms. If necessary, expand the octet on the central atom to lower formal charge.a. PO43- b. CN- c. SO3 2- d. ClO2 -arrow_forwardWrite Lewis structures that obey the octet rule for each of the following. a. HCN b. PH3 c. CHCl3 d. NH4+ e. H2CO f. SeF2 g. CO2 h. O2 i. HBr Except for HCN and H2CO, the first atom listed is the central atom. For HCN and H2CO , carbon is the central atom.arrow_forwardWrite an appropriate Lewis structure for each compound. Make certain to distinguish between ionic and molecular compounds.a. Al2O3 b. ClF5c. MgI2 d. XeO4arrow_forward
- Which of the molecules and polyatomic ions cannot be adequately described using a single Lewis structure? A.O3 B.HCN C.CO2−3 D.OF2 E.CH2Cl2 F.NH+4arrow_forwardWrite an appropriate Lewis structure for each compound. Make certain to distinguish between ionic and molecular compounds.a. BI3 b. K2Sc. HCFO d. PBr3arrow_forward5. Write the chemical formula that results when the following pairs of ions combine to form an ionic bond. a. Sr2* and 02- b. Mn4 and O2- C. Lit and CI- d. Cst+ and Sz-arrow_forward
- 2. Avogadro does not "waste" his time drawing a Lewis structure before determining the shape of PF3. He thinks that the shape of PF3 must be trigonal planar because there are three fluorine atoms bonded to the central phosphorus atom. a. Draw the Lewis structure for PF3. b. Was Avogadro's answer for the shape of a PF3 molecule correct? Explain c. Why is it important to draw the Lewis structure for a molecule before identifying the shape of the molecule?arrow_forward2.
