Excellent presentation, with clear concepts. I'm a 77-year old, retired electrical engineer. Had studied organic chemistry in my inter-science(today's 12th std). Though teachers in my college were good, the way you are explaining is superb. I really envy the milleniums. With teachers like you they need not go to any coaching classes.
List of priority - COOH (carboxylic acids) - CHO (aldehydes) - (ketones) - OH (alcohols) - yne (triple bond) - ene (double bond) - Cl, Br, (halogen group) - CH3- C2H5 (methyl, ethyl) So the answer should be 3,4-dibromopentanal because the functional group is an aldehyde and not a ketone
This is best explanation I could find on TH-cam. Literally our school teachers just couldn't explain this in simple language. And moreover they didn't even bother tell us about the rules, priorities, etc. I think you deserve more sir. Love you from India.
My school teachers are even worse. They basically decided that we understood their lecture so they gave out a few half assed example out of the book to make us believe we got it. But we never did. It was like they described a memo instead of teaching us how it came to be
Guys, this thing is kinda confused, let, watch over it carefully, " I think the numbering we should used is the backward one, I mean the one that starts from the (aldehyde), because it's the functional group that has the smallest number which is 1, and the largest, if we're to look at it in a forward numbering it is 5, while bromine in backward numbering are, 3,4. If we're to look at it in a forward numbering it's 2,3. So we'll rather use the backward numbering which starts from the (aldehyde) then our bromine numbering will be 3,4 respectively, let check the example our tutor did for (4-chloropentanoic acid) for better understanding. Thanks 👍
This video is exactly what I've been looking for: Someone taking it gradually step by step, example by example while adding more rules along with examples. This is the best way to explain it
This is such a cool idea! I'm a chemistry prof in the US working on a similar approach on my channel. I like breaking down the concepts by videos, and giving an introduction to a topic (e.g., SN1 reactions) in 5 min or less!
it's 3,4-dibromopentinal, because of the priority list where aldehydes (O=C-H) are 2nd, so we will be using the numbering where aldehydes are the first one (right to left)
i am a professor of Organic Chemistry PhD course at OXFORD UNIVERSITY and from the following content, all is correct except he forgot to mention that naming rules should also be applied in giving the Nomenclature of the organic compounds. So the correct answer is 3,4-dibromopentanal and no capital letters, spacing or hyphen between letters /numbers should be applied. the hyphen should only be between a number and a letter.
the answer is 3,4-dibromopentanal. I thought it is 2,3-dibromopentanal but because of the priority list, and the aldehyde being the 2nd priority after acids, position number 1 is on the right, which is the aldehyde.
Thanks a lot sir... This really helped me a lot... I'm studying in class 10 and tomorrow is my chem pre board exam...😭 I Didn't know anything about organic chemistry😅... But now I hv understood it... Hats off to you sir... Last answer is 3,4-dibromo pentanal. According to me..

Excellent video with clear explanations and a good pace. It’s 3,4-dibromopentanal. Aldehyde takes priority over bromines, and 1 not needed for the -al.
It is " 3,4-dibromo pentanal " 31:53 25:45 As we can see the c=o has more priority than Cl or Br, so the naming will start from the keton itself (c=o). ❤️
@@naniplayz2977 Answer: 3,4-dibromopentanal Not pentanone as Ketone cannot be placed at the end of carbon chains. Only Aldehyde i.e. -CHO can be at the end. Also, don't forget the priority list that we have to start the naming from the functional group! hope it helped :D
3,4-dibromopentanal (Functional group is an aldehyde, bromide is present on carbon 3 and 4, the chain is 5 carbons long and the carbons have single saturated bonds i.e. Alkane)
3,4-dibromo pentanal It wont be 2,3- dibromo pentanal because we have to consider the priority list. The aldehyde group (H-C=O) comes before the halogen functional group.

@@jhuleaalexisiraula10-scept40 it's 3,4-dibromopentanal because you have to obey the priority list.. and an aldehyde comes before halogens on the list, therefore numbering will be backward. This is the type of teacher I want for myself. Keep it sir

For those Who don’t understand how the answer is 3,4- dibromo pentanal instead of 2,3- dibromo pentanal . So please check the priority list at 24:39 on 3 no , you will see the priority of ketone is more then the priority of halogens ( chloro , bromo , Floro, Iodo ) which is at 7 no . So it is necessary to start counting from ( Right to Left ) and from down side so u will observe that the answer is Come at no 3 and 4 . 🫶🏻🙌
