N ow that we're familiar with the structure and preparation of alkenes, let's look at their chemical reactions. The characteristic reaction of alkenes is addition to the double bond according to the general equation:
6. 1 An atomic model is needed to understand how atoms bond Electrons in the outermost occupied shell of any atom are responsible for the atom's chemical properties. The electrons that participate in chemical bonding are called valence electrons(价电子), the shell they
SOLUTIONS TO TEXT PROBLEMS 19.1 (b) The four carbon atoms of crotonic acid form continuous chain. Because there is a double bond between C-2 and C-3, crotonic acid is one of the stereoisomers of 2-butenoic acid. The chem
