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.
Ch18 Ketones and Aldehydes (landscape) Page 5 A ketone or aldehyde group can also be named as a substituent on a molecule with another functional group as its root. The ketone carbonyl is given the prefix oxo -, and the aldehyde group is named as a formyl-group.(This is especially common for carboxylic acids).h18 Ketones and Aldehydes (landscape) Page 13 However, to circumvent this problem, carboxylic acids can be converted first into a functional group that is easier to reduce than an aldehyde group. The group of choice is an acid chloride.
