  As a Clarification for all students #19: To clarify the correct answer is decreasing temperature due to less collisions. I was attempting to explain every situation outlined in the problem and ended up circling the increasing answers by mistake. #26: Is asking for the conjugate base. I should have choose NH2-. All my organic and biochemistry knowledge took over and I went with the common answer by mistake.

• 
  @QueenHouse31.Ай бұрын

  For question 19, you said lowering the temperature is the only one that would decrease the rate of reaction, yet you chose answer D for increasing concentration and adding a catalyst. Are you sure that answer was correct?

• 
  @ItsDrDanАй бұрын

  Lowering the temperature would decrease the rate of reaction. I was trying to explain when each answer would be True... and in the moment circled the increasing answers versus the decreasing answers. One of my students pointed that out to me yesterday. I also misread #26... It asks for the conjugate base which is technically NH2- .... the conjugate acid is NH4+ (I was thinking of normal acids/bases in my head) didn't catch them when I was editing all the footage

  For menthol, there would be a chiral center on the carbon connected to the methyl group, another on the carbon connected to the isopropyl, and the third would be on the carbon connected to the alcohol

  @@ItsDrDan carbon connected to methyl that carbon has two same CH2 and One H and methly, as it has two same CH2 so how it can be chiral?

• 
  @ItsDrDan2 ай бұрын

  @chemistrybysaadanwar O I see your question now… so your right it would CH2 on both sides, but ring structures are special. You need to compare both sides of the ring. So, I will compare the CH2’s like you said. They are the same… you then move to the next set of carbons on the ring… compare them. This is where one has an alcohol group. Creating a chiral center on the original carbon. If the molecule was just isopropyl-4-methyl cyclohexane without the alcohol group… it would end having no chiral centers at all. You always have to compare both sides of the ring like two sides of a coin

  Thank you for the video Dr.Dan. I would just like to confirm the measurement reading for the block, was it measuring at 1.70 or .70? I noticed that it's past the 1 before the 2.

• 
  @ItsDrDan2 ай бұрын

  It would be measuring 1.70, but the length would just be 0.70 being that I started at 1. Usually, the rulers in the lab will be fine to start at 0, but it's pretty common where tape measures that you purchase at like Home Depot are not always calibrated correctly at the end. So, usually... I always start at 1 and just subtract it from the length... if that makes sense

•

  I believe so. I cant think of any ketohexose that would not be considered a furanose. Being that the definition is just a 5 member cyclic ring with an oxygen in it and an anomeric carbon.
