Chapter 16 Aldehydes and Ketones
... An aldehyde cannot have the molecular formula C5H12O. C5H12 has too many H’s. Since an aldehyde has a double bond, the number of C’s and H’s resembles an alkene, not an alkane. An aldehyde with 5 C’s would have the molecular formula C5H10O. ...

Alcohols, Ethers, and Epoxides
... The bond angle around the O atom in an alcohol or ether is similar to the tetrahedral bond angle of 109.5°. In contrast, the C – O – C bond angle of an epoxide must be 60°, a considerable deviation from the tetrahedral bond angle. For this reason, epoxides have angle strain, making them much more re ...

Elias James Corey
Elias James ""E.J."" Corey (born July 12, 1928) is an American organic chemist. In 1990, he won the Nobel Prize in Chemistry ""for his development of the theory and methodology of organic synthesis"", specifically retrosynthetic analysis. Regarded by many as one of the greatest living chemists, he has developed numerous synthetic reagents, methodologies and total syntheses and has advanced the science of organic synthesis considerably.
