The octan- part of the name tells us that the LCC has eight carbon atoms. been selected on the basis of sound scientific judgment. Butanol is oxidised by sodium dichromate (Na 2 Cr 2 O 7) acidified in dilute sulphuric acid to form the aldehyde butanal. Butanal. There is a chlorine (Cl) atom on the seventh carbon atom; numbering from the carbonyl group and counting the carbonyl carbon atom as C1, we place the Cl atom on the seventh carbon atom.
