Thank you sir ❤❤
Thanks a lot man I couldn't find it anywhere ❤
why numbering is not starting from nitro group carbon
If we start numbering from the nitro group then the position of the substituents are at 1, 2, and 5 for -NO2, -F, and -C2H5, respectively, when we go counter-clockwise. On the other hand, if we go clockwise then they are at 1, 3, and 6. Both of these positions are higher compared to 1,2,4 (when we start from fluorine and go clockwise). NO2 is not a functional group. Therefore, we don't need to give preference to NO2.

Very good explanation 👍
Thank you 🙂
First Of All Thanks , It's Really Helpful for us Neet Students hope you do well in future !
Sci Finder editorial team reviewed this case and the naming issue is fixed in their records as of Aug. 12, 2024.
2-methylbutanal has a chiral carbon at 2-position. Therefore, it can be considered as two isomers (R and S configuration) if the question says write down all isomers including configurational.
