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% |
formalin is what percentage aqueous solution of formaldehyde by volume? | 40% |
