QuestionAnswer
Aldehydes are prepared by the oxidation of a primary alcohol
an organic group containing one or more -CHO groups aldehyde
What is the functional group for the aldehydes? carbonyl group (-CHO)
general formula for the aldehydes R-CHO
where is the functional group located on the carbon chain for the aldehydes? at the end of the carbon chain
methyl alcohol oxidizes to form formaldehyde
the molecular formula for formaldehyde HCHO
another name for formaldehyde methanal
a three-carbon chain aldehyde would be called propanal
formaldehyde in water is known as formalin
formalin is what percentage aqueous solution of formaldehyde by weight? 37%
