- phosphogene ,Cl2=O, has a smaller dipole moment than formaldehyde,H2C=O even though it contain electronegative chlorine atoms in place of hydrogen .Explainarrow_forwardWhy H2O is dipolar whereas BeF2 is not.arrow_forwardThere are three different dichloroethylenes (molecular for-mula C₂H₂Cl₂), which we can designate X, Y, and Z. CompoundX has no dipole moment, but compound Z does. Compounds Xand Z each combine with hydrogen to give the same product:C₂H₂Cl₂ (X or Z) +H₂→ClCH2-CH2Cl What are the structures of X, Y, and Z? Would you expect com-pound Y to have a dipole momenarrow_forward
- The cyanate ion is an anion consisting of one oxygen atom, one carbon atom, and onenitrogen atom, [OCN], in that order. a) Write three (3) resonance contributing structures for the cyanate ion. Show formalcharges.b) Based on your contributing structures, predict the O-C-N bond angle.arrow_forwardExplain what is wrong with each of the following statements. a. “A bond is a double bond. b. “A bond consists of four electrons, one in each of the four p orbitals involved in the bond. c. “A bond is twice as strong as a bond because it consists of two orbital overlaps insteadof just one.”arrow_forwardExplain how there can be two kinds of bent: “bent-109.5o” and bent-120o,” and give an exampleof each from the previous question. (Note that “bent-109.5°’ is more common than “bent-120°.”)arrow_forward
- What are the bond angles predicted by the VSEPR model about the carbon atom in the formate ion, HCO2? Considering that the bonds to this atom are not identical, would you expect the experimental values to agree precisely with the VSEPR values? How might they differ?arrow_forwardThe curved arrow notation introduced in Section 1.6B is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions.Because each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCl.arrow_forwardAre the H-N-H bond angles in NH4+ the same or different than all of the bond angles in NH3? Please explain.arrow_forward
