What is the bond length between carbon and oxygen in an aldehyde molecule?
The bond length between carbon and oxygen measures approximately 120 to 122 picometers. This specific distance defines the structural integrity of the functional group.
Questions about Aldehyde
Short answers, pulled from the story.
How does infrared spectroscopy identify aldehydes compared to other organic compounds?
Infrared spectroscopy reveals a strong carbonyl band near 1700 inverse centimeters for aldehydes. These spectral features distinguish aldehydes from other organic compounds.
What industrial process prepares diverse aldehydes on a very large scale?
Hydroformylation represents one dominant technology for preparing diverse aldehydes on a very large scale. This process involves treating an alkene with hydrogen gas and carbon monoxide using a metal catalyst.
Why are alpha hydrogens in aldehydes more acidic than those in ketones or alkanes?
An alpha hydrogen in an aldehyde exhibits weak acidity with a pKa near 17. This value is much more acidic than alkane or ether hydrogen which has a pKa near 50 and even more acidic than ketone alpha hydrogen with a pKa near 20.
How many tons of formaldehyde are produced annually on a global scale?
Formaldehyde production reaches about 100 million tons annually on a global scale. It serves primarily in resin production combined with urea, melamine, or phenol.
