Each H atom (group 1) has 1 valence electron, and the O atom (group 16) has 6 valence electrons, for a total of 8 valence electrons. 2.

The catalytic ability of Lewis acids, such as hydrogen, halogen, chalcogen, and pnictogen bonded species, is traditionally attributed to the lowering of the LUMO of the activated dienophile, resulting in a smaller, i. e., more favorable, HOMO diene-LUMO dienophile energy gap and hence stronger orbital interaction. 14 Recently, however, we have shown that this rationale is incomplete.

Acrolein is the simplest unsaturated aldehyde. It is a colorless liquid with a foul and acrid aroma. The smell of burnt fat is caused by glycerol in the burning fat breaking down into acrolein.
