Reduction: aldehyde + hydrogen --> pri. Alcohol Form of addition reaction.
Reduction: aldehyde + hydrogen Break hydrogen bond
Reduction: aldehyde + hydrogen Break double bond and use electrons to bond with hydrogen.
Reduction: aldehyde + hydrogen Brief Method
Hemiacetal and Acetal Functional Groups Hemiacetal: alcohol and ether on same carbon Acetal: Two ethers on same carbon
Hemiacetal Synthesis: aldehyde + hydrogen Alcohol + aldehyde --> hemiacetal Ethanal + methanol Alcohol oxygen becomes an ether Carbon double bond oxygen becomes an alcohol
Synthesis of Acetal Functional Group Acetal: alcohol plus hemiacetal (ether synthesis) Acetal: Two ethers on same carbon
