Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Dear Imran, let me tell you something and I want you to note it down in your notes, 'sp hybridised carbon is even more electronegative than sp3 hybridised Nitrogen and sp hybridised Nitrogen is more electronegative than sp3 hybridised Oxygen'. In acetylene, there's 50% s-character, therefore it is acidic. Rest, other hydrocarbons are not very electronegative due to low percentage of s-character! In Pauling scale, Carbon's electronegativity is around 2.5 only, which is low. Hope this helps. 😊
Imran, accept the answer! 🙏
