As a footnote to Mark M. Green’s letter on how to make organic chemistry “be part of understanding the wider world, to be worth knowing” (Jan. 2, 2023, page 3), I wish to illustrate my approach to “a ...

Complete combustion of alkenes produces carbon dioxide and water, provided there is a plentiful supply of oxygen. Incomplete combustion of alkenes occurs where oxygen is limited and produces water, ...
