The ChemDoctor: Peter deLannoy

IMG_2567

 

ChemDoctor is an educational web site committed to providing a free world class education in chemistry. The vision is to provide short chemistry videos that the viewer can use to learn chemistry. Current offerings include a large range of videos extending from the high school chemistry curriculum through university level general chemistry. The inspiration for ChemDoctor came from the Khan Academy and the viewer will notice the similarity of the platform used for instruction. In addtion to this web site more chemistry videos can be found at ChemDoctor.

ChemDoctor is devoted to helping you understand chemistry through the use of chemistry videos. Simply click on the link and you should find the video lesson you need. If not, leave a comment here or contact me at ChemDoctor or chemdoctortutoring@yahoo.com and I will do what I can to rapidly produce the lesson you want.

The best way to use the videos is to perform the calculations pausing the media as needed. I also recommend having a periodic table handy.

    1. Hey Manal,

      Thanks for using chemdoctor. I hope it helps you with your studies. If there are other videos you would like produced you can reply here. Glad you are using the site!

  1. Hi,

    You have a wonderful resource here. I have a suggestion, though. Perhaps for a beginner who might not have any idea where to start you could create a list of suggested links in a logical order so they could move through the videos and learn in an organized way? Even 4 or 5 suggestions as places to start on this page would be helpful.

    Thanks!

    1. Hello Roberta,

      Thanks for visiting my site and the useful comment. Presently I have been consumed with generating content and getting my site up and running and hadn’t given much thought to other ways the content might be used. Over the next year I hope I can address those kinds of issues. Perhaps this summer I can follow up on your suggestion. Thanks again for using my site.

  2. Hi Dr. Pete,

    Thanks for all the help this year! The videos were good review for the Test (hello, AP Chem!).

  3. Dr Pete,
    Thank you so much for these videos! They are really helping me for comp review. I have learned so much this year in chemistry!

  4. Thanks for all the help you have given to us. All of your hard work putting these videos together is appreciated by all your viewers.

  5. Thanks for taking the time to put together these wonderful videos. It is great to know my teacher is so dedicated and is always there to help me.😀

  6. Hello! Someone in my Facebook group shared this website with us so I
    came to look it over. I’m definitely enjoying the information.
    I’m book-marking and will be tweeting this to my followers!
    Terrific blog and amazing design and style.

    1. Lizzy,

      I owe you an apology because when I started this project I intended to have general chemistry done in one year and be on my way into o-chem by now. Alas, this is not the case. The one piece of advice I have for you is to evaluate the strength of the nucleophile and the structure of the electrophile. SN2 reactions tend to happen between strong nucleophiles (strong bases) and simple electrophiles with good leaving groups. When you combine a strong nucleophile with a complex electrophile (secondary and tertiary electrophiles) E2 usually result. On the other hand, complex electrophiles usually form stable carbocations under the right solvent conditions and then, depending on the nucleophile, either follow E2 or SN1 pathways. This may seem like Russian to you. I apologize again for not supporting you yet. That will change in the future. Thanks for visiting my site and please check back.

  7. Hey Pete, I am digging the web site. But I have a small, but huge problem. My students can’t access you tube. Is there another format you can put the videos in? They will have access to everything at home which is awesome, just not at school, but I guess that is what I am here for right? Thanks for the great resource.

    1. If the school is blocking the youtube I’m not sure what I can do although I am thinking about your problem. Its not something I anticipated. One thing you might consider is to start flipping your classroom where you assign certain videos as actual lessons for homework and then go active in the classroom with white boarding and or group work using problems. In the beginning thats why I started producing the videos but there were some issues…I would be glad to describe in a nonpublic forum that are school related. But I was inspired by the Khan Academy and decided to go in that direction as an independent entity. I’ve now started flipping my classroom using the videos. I’m doing it a little bit at a time trying to figure out the best tactics. If you want to talk more we can go private.

    1. The test is comprehensive. There will be 20 multiple choice and 1 FRQ. The test will focus on chapter 4: Types of Reactions. You should expect all manner of stoichiometric calculations with an emphasis on redox, neutralization, and precipitation reactions.

  8. Hey Mr. Pete
    I can’t find the videos on balancing chemical formulas on your website to help me on my homework. Can you please tell me where to look? Thanks.

    1. If you look under the link for Chemical Equations (Stoichiometry) you will find balancing for specific reactions. The balancing of alkanes, decomposition and synthesis reactions is recommended.I will post more videos in this area soon.

  9. Hey Dr. Pete. I just wanted to know the test topics for the Honors chem test on Monday. I assume that it is cumulative. Will the stuff on the lab be on the test.

  10. Thank you for the videos, they were all so helpful. They will help for the test I’m about to take and for future tests. Also, thank you for taking time out of your own personal time and making those great videos for me.

  11. Dr. Pete.Will it be better to add practice problems for us to take so we can see if we really understood the concepts from your videos so it can really prepare us for any chemistry exam we will be taking in honors chem and help us get a 3 or above on the ap chem(the test we are worrying about).
    Your help will always be appreciated and your videos will help us for the ap.Thank you

    1. Hello Shaiyan,

      I agree with you. I have to say that making the videos interactive is my goal for this site. So keep an eye on the new videos that are posted this year. Thanks for using my site. Please spread the word!
