Problem 54

The diatomic molecule OH exists in the gas phase. The bond length and bond energy have been measured to be 97.06 pm and 424.7 kJ/mol, respectively. Assume that the OH molecule is analogous to the HF molecule discussed in the chapter and that molecular orbitals result from the overlap of a lower-energy pz orbital from oxygen with the higher-energy 1s orbital of hydrogen (the OH bond lies along the z-axis). a. Which of the two molecular orbitals will have the greater hydrogen 1s character? b. Can the 2px orbital of oxygen form molecular orbitals with the 1s orbital of hydrogen? Explain. c. Knowing that only the 2p orbitals of oxygen will interact significantly with the 1s orbital of hydrogen, complete the molecular orbital energy-level diagram for OH. Place the correct number of electrons in the energy levels. d. Estimate the bond order for OH. e. Predict whether the bond order of OH will be greater than, less than, or the same as that of OH. Explain.

Step 1 of 3

Degenerative Change with Age ● Body dimensions and composition, skin, hair, skeletal, vascular, respiratory, neurological, immunological, our senses...all change ● Involves gradual molecular­level change, which then affects cell, tissue, organ, and/or system function. Body shape and size ● Peak body height in 20s, then gradual decline ● Peak weight in 40s, then gradual decline ● Peak BMI (weight/height^2) by 65, then decline. ● Decline in fat­free or lean mass (FFM), increase in fat (FM) ● Relocation of fat: ­ men=guts ­ women=hips/thighs Skin/Hair ● Reduced microcirculation ● Thinning and welling ● Hair follicles­sweat glands Cardiovascular ● Reduced oxygen absorption ● Vascular stiffening/obstructions ● Reduced cardiac function Musculo­Skeletal ● Spinal compression ● Calcium leaching ● Reduced bone production ● Muscle mass, fibers, enervation Guts ● Reduced organ elasticity ● Reduced mineral uptake ● Micro­flora changes ● Reduced peristalsis ● Reduced kidney function ● Bladder elasticity ● Sphincter enervation The Senses ● Lens discoloration ● Presbyopia ● cataracts/glaucoma ● Reduced sense of smell ● Reduced sense of touch Why try to understand why Or.. great excuses for biological research ● Helps people live longer..and longer and longer (extending life span­longevity) ● Helps people age with better health (extending “health span”) ● Helps people look better Along the way (anti­aging, un­aging, and the pursuit of youth) Degenerative Change with Age ● Body dimensions and composition, skin, hair, skeletal, vascular, respiratory, neurological, immunological, our senses...all change ● Involves gradual molecular­level change, which then affects cell, tissue, organ, and/or system function.
