Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

E. J. Coreys 1964 total synthesis of -caryophyllene (essence of cloves) solves a number of problems of construction of unusual-sized rings. The first step uses an efficient photochemical [2 + 2] reaction. The desired stereochemistry and regiochemistry had been predicted based on model reactions. (a) [2 + 2] Reactions are quite common in photochemical reactions. Would this reaction be predicted to occur in the ground state? The next steps follow. Basic alumina is a chromatography support that will often act as a base catalyst. (b) What is the mechanism of the first step? (c) What is the mechanism of the second step?
