You'll probably want to hide YouTube's captions if using these subtitles. A functional group is a group of atoms and bonds that possess a predictable chemical behaviour. We're gonna cover the most common functional groups that you will see in a college organic chemistry class And you can group them into 3 categories. The first category will have carbon with multiple bonds So lets look at an example where carbon has more than 1 bond. Well if carbon is bonded to one other carbon atom, we've already referred to this as an alkene. If i were to complete my dot structure over here, I would know that i need two more bonds on my carbons like that And those could be connected to just not anything, so we're gonna put an R group here to represent the fact that there could be just anything attached to the carbons And R stands for the rest of the molecule, or the remainder of the molecules. Usually we are talking about carbons and hydrogens here but could be 1 carbon, 2 carbons or 5 carbons It doesnt really matter. It just allows us to focus on the alkene functional group Questions Tips & Feedback Be specific, and indicate a time in the video: At 5:31, how is the moon large enough to block the sun?
