Yaar syllabus hi karna hai toh kal khatam kar du kya? Achcha tarah padhna hai ya uda du main pura? Dimaag kharab kar diya hai yeh question puch puchke. I aim for Feb end. Tumhare exams April mein hai. You'll have heck of a time to revise the topics.

Listen Shivangi. I'm sorry for whatever I had said. I don't even know who you are! But the same question again and again pisses me off. I never ever get angry but this time; it really got me.

in the last question u told we need just alc. KOH to convert a terminal alkyne into a non-terminal alkyne but alc.KOH being weak cannot convert alkene into alkyne so that's why we use NaNh2 also.so we need both na alc.KOH and NaNh2 ?

oh damm....i forgot his lessons....refer notes buddy....if we take excess NaNH2 with a non terminal alkyne after which we attavk them with 2moles of CH3I.....we get non terminal alkyne from terminal alkyne

watch prep of alkyne video again ...ur doubt will be solved for sure
This question is for previous slide sir plzz answer Sir which reagent is used for dimerisation? Also sir in slide 2 if we had done hydride shift we would have got a conjugated system (i.e resonance would have been possible) so why didnt that product form?

bro....if i could be helpful....watch carbonyl video...in that there is a reaction with reagent Cu2Cl2/Nh4Cl....that does dimerisation...reply if i am wrong...

But in that video only sir told that this is not dimerisation. U can listen that once again.
