The general formula for the alkanals is
ROH
R2CO
RCOOR1
RCHO
Forklaring
ROH - Alkanols
R\(_2\)CO - Ketones
RCOOR\(^1\) - Esters or alkanoates
The general formula for alkanals is C\(_n\)H\(_{2n+1}\)CHO, where n = 0, 1, 2, 3, and so on. In other words, it is RCHO
Alkanals are compounds that are formed when long-chain primary alcohols are oxidized. Primary alkylsulphates biodegrade to produce these alcohols.
