Muscle Insertion. The insertion of the muscle is the end of the muscle attaching to the freely moving bone of its joint. To understand muscles and joint movements, there are four things to keep in mind: Movement happens at joints, with one bone of the joint moving freely while the other remains relatively stationary.
Aldehyde vs Ketone. Aldehydes and ketones are known as organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen. The carbonyl carbon atom is sp2 hybridized. So, aldehydes and ketones have a trigonal planar arrangement around the carbonyl carbon atom. The carbonyl group is a polar group, thus, aldehydes and ketones have higher boiling points compared to the hydrocarbons having the same weight.
3. Ketone Functional Group. A ketone is a carbon atom double bonded to an oxygen atom that appears as a bridge between two other parts of a molecule. Another name for this group is the carbonyl functional group. Note how the aldehyde is a ketone where one R is the hydrogen atom.
