Residual Molar Entropy

Postby Shweta Chawla 2D » Fri Jan 29, 2016 11:42 am

For residual molar entropy, specifically for organic molecules, how can we determine the structure, due to the number of isomers and the subsequent number of positions for each isomer?

Use the equation klnW. (Because many organic compounds specify how to draw each one, there are limited ways of drawing them). Count up the different ways and use the equation.

One example of this type of problem was on one practice quiz asking for the residual molar entropy of one mole of c6h5br. We are able to use the klnW equation here after calculating the value of w. There are six possible states for carbon so W would simply be 6^avogadros number.

The above discussions are correct. Well done!
