In the first conformation,
there are 2 gauche CH3/CH3 interactions ,
therefore total energy is equal to (0.8+0.8) Kcal/moles = 1.6Kcal/moles.
For the second conformation,
there are 1 CH3/CH3 eclipsed interactions, 1 CH3/H eclipsed, 1 H/H eclipsed and 1 CH3/CH3 gauche interactions ,
therefore total energy is equal to (4.1+1.2+1.0+0.8) = 7.1Kcal/moles
Energy difference = 7.1-1.6
= 5.5Kcal/moles
Add Answer to:
17. Given the following energies in kcal/moles (CH3/CH3 eclipsed-4.1, CH3H eclipsed = 1.2, H/H eclipsed =...

Use the following tide table to answer the questions in the
Assessing Your Learning section of this lab. This tide table shows
the predicted ocean heights for Santa Cruz/Monterey Bay, California
during December 2011.
1. A visit to Santa Cruz/Monterey Bay, California is planned
during the week of December 4-10 to view the tide pools. To observe
intertidal animals during the daytime at the lowest possible tide,
the best time to visit the beach is on _________________ at
