Experiment #9 – Identification of Aldehydes and Ketones Introduction Aldehydes and ketones share the carbonyl functional group which features carbon doubly bonded to oxygen. In the case of ketones there are two carbon atoms bonded to the carbonyl carbon and no hydrogens. In the case of aldehydes there is at least one hydrogen bonded to the carbonyl carbon; the other attachment may be to a carbon or a hydrogen. In all cases the carbon(s) that are attached to the carbonyl group may be aliphatic (not

Name ________________________ Lab 1. Volcanic Hazards VOLCANOES INTRODUCTION Few things excite the imagination as much as a volcanic eruption‚ one of nature’s magnificent spectacles‚ which can result in devastating consequences. The very word “volcano” brings to mind thunderous explosions‚ rivers of fiery orange lava‚ and images of smoking destruction. The actual capacity for destruction is not overrated -- volcanic eruptions are one of the most devastating of all geologic hazards. There
