Need help balancing some equations
« on: April 16, 2012, 05:35:49 PM »
For lab I am supposed to write balanced equations for maleic anhydride with.... water, cycloyhexanol, aniline and isoprene. I am struggling with the product part, I am not quite sure how the bonding will work. Can anyone help/give any tips. Thank you in advance

Can you identify a nucleophile and an electrophile?

In all of them the maleic acid is the electrophile and the other compound is the nucleophile

If water is the nucleophile, one of the protons will have to move onto the leaving group at some point to make the final product.  What do you think that the product is?

An acid anhydride and water are the products of two moles of acid.  This problem has a slight wrinkle, because a single molecule has both carboxylic acids and the formation of an anhydride from this molecule is intramolecular.
