Draw the correct structure of the indicated product for each reaction. The starting material is a 4 carbon chain where carbon 1 has a bromo substituent and carbon 3 has a methyl substituent. This reacts with K C N to form product 1. Product 1 reacts with hydroxide and water, followed by H 3 O plus to give product 2.

there is none because earth is stationary and flat.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
