This molecular shape is essentially a tetrahedron with two missing vertices.

The transfer of this electron produces the Cs + ion, which has the valence electron configuration of Xe, and the F − ion, which has a total of eight valence electrons (an octet) and the Ne electron configuration.

The compounds in the figure 1 are found chiefly in plants or microorganisms and those in the figure 2 have animal origins. In this case the change of the stereochemistry causes a drastic change in the perceived scent. In particular, 2-Heptanone provides part of the sharp scent from blue cheese and (R)-Muscone is part of the musky smell from the Himalayan musk deer.

These structures can be found in many aromatic compounds contributing to smell and taste.

Notice that the boiling points of the unbranched alkanes (pentane through decane) increase rather smoothly with molecular weight, but the melting points of the even-carbon chains increase more than those of the odd-carbon chains.

Enolates undergo 1,4 addition to α, β-unsaturated carbonyl compounds is a process called a Michael addition. The reaction is named after American chemist Arthur Michael (1853-1942).

Although there are many types of carboxylic acid derivatives known, this article focuses on four: acid halides, acid anhydrides, esters, and amides. The relative reactivity of carboxylic acid derivatives toward nucleophile substitutions is related to the electronegative leaving group’s ability to activate the carbonyl.

Because the methyl group is larger and has a greater 1,3-diaxial interaction than the chloro, the most stable conformer will place it the equatorial position, as shown in the structure on the right.
