"At 8:39, Ram you said COOH means 2 oxygen and 1 hydrogen, then it should not be Carboxylic acid cause it contains 3 oxygen right double bond. It should be in the Aldehyed group right?"

Please check the structure of -COOH. It is a carboxylic acid and carboxylic acids always have 1 carbon, 2 oxygen and 1 hydrogen as the functional group. Aldehyde group (-CHO) always has 1 carbon, 1 oxygen and 1 hydrogen as the functional group.

Lesson 5: Functional groups

Functional groups

Google Classroom

Functional groups are group of atoms or bonds that define the function of the hydrocarbon that they get attached to. Examples: Alcohol, Aldehyde, Ketone, Carboxylic acid, Halogens, Double & Triple covalent bonds. Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more.

At
1:12
to
1:14
, how will that molecule give off H+ ions? Its a covalent bond, and hence should not dissociate into ions!

Isn't OH hydroxyl? Why are we calling it alcohol? Why the special name?

  You're right, OH as a functional group is hydroxyl, and compounds with the hydroxyl group are called alcohol. So hydroxyl will be OH while alcohol would be ROH. I think this correction should be made so you could add it in the "Tips & Thanks" section too!

Could the ketone group be at the end of the parent carbon chain too, by having a double bond with the adjacent carbon?
