22. What is the molecular shape of methane (CH₂)? a. planar or flat, with the four H extending out from the carbon b. pentagonal, or a flat five-sided arrangement c. tetrahedral, with carbon in the corner d. circular, with the four Hattached in a ring around the carbon e. linear, since all the bonds are nonpolar covalent bonds 23. The ability of morphine to mimic the effects of the body's endorphins is due to a. a chemical equilibrium developing between mor- phine and endorphins. b. the one-way conversion of morphine into endorphin. c. molecular shape similarities that allow morphine to bind to endorphin receptors. d. the similarities between morphine and heroin. center and H at each e. hydrogen bonding and other weak bonds forming between morphine and endorphins. 24. Which of the following molecules or compounds would you predict is capable of forming hydrogen bonds? a. CH₂ b. CH₂O c. NaCl d. H₂ e. a, b, and d can form hydrogen bonds. 25. Chlorine has an atomic number of 17 and a mass number of 35. How many electrons would a chlo- ride ion have? a. 16 b. 17 c. 18 d. 33 e. 34 26. Taking into account the bonding capacities or va- lences of carbon (C) and oxygen (O), how many hydrogen (H) must be added to complete the fol- lowing structural diagram of this molecule? oxc-c C-C-C-C-C-C a. 9 b. 10 c. 11 d. 12 e. 13 22.
