What is the energy difference between the two lowest-energy conformations of 2,3-dimethylbutane?
  1.the energy of one gauche interaction
  2.the energy of two gauche interactions
  3.the energy of two H  CH3 eclipsing interactions
  4.the energy of three H  CH3 eclipsing interactions
  5.the energy of two CH3  CH3 eclipsing interactions

Question 2

The lowest energy conformation of decane resembles a straight rod. It is a fully stretched zig-zag conformation with all bonds staggered and all large substituents anti to each other. Imagine we bend this chain at carbon 5. What is the minimum strain that such a once-bent conformation (bent rod) must have?
  1.3.8 kJ/mol
  2.4.0 kJ/mol
  3.6.0 kJ/mol
  4.0.0 kJ/mol
  5.11.0 kJ/mol

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
