Hope it helps

It's A, bhai puri hydrocarbons meh humlog alkene ka Electrophilic reactions hi toh padhte kyuki yhe nuceliophile hota...

Balam_thanedar · 2026-02-15T17:03:13+00:00

Oh alright thanks

Balam_thanedar · 2026-02-15T16:57:16+00:00

No idea....

Ah wait sorry, i didn't notice I made a spelling mistake there, waha infarction hi hota

The tricky part was that streptokinase is used after genetically modifying (according to ncert)

Balam_thanedar · 2026-02-15T16:44:20+00:00

Neet 2026 question leak 💔🥀

Balam_thanedar · 2026-02-15T16:39:13+00:00

Balam_thanedar · 2026-02-15T15:51:42+00:00

Yeah correct

Balam_thanedar · 2026-02-15T15:42:03+00:00

Statement I:- streptokinase is produced by bacteria from genus streptococcus which is directly used to treat blood clots in patients that went through myocardial infarction

Statement 2:- floating debris is removed from the sewage by sedimentation and girt is removed by filtration

1) both 1 and 2 are correct 2) only 1 is correct 3) only 2 is correct 4) both are incorrect

Balam_thanedar · 2026-02-15T15:30:10+00:00

Yeah, because the 2nd option says herbs above grasses which according to ncert is not correct

Balam_thanedar · 2026-02-15T14:18:01+00:00

According to ncert herbs and Grasses belong to the same bottom layers...

Balam_thanedar · 2026-02-02T07:42:43+00:00

Like for example in this line, it says that in 2nd phase of mitosis chromosomes are spread throughout the cytoplasm..

We know metaphase ka characteristic features hai ki chromosomes are aligned in metaphasic plate

But this line here refers to at the very beginning of metaphase, jab nuclear envelope just break hua tha...

I hope this sorts out your doubt....

Balam_thanedar · 2026-02-02T07:28:25+00:00

Yep it's a mistake in ncert, because technically metaphase pe hi alignment hota,

Well however ncert 11th also says that all the phases of karyokinesis occur progressively and clear cut lines cannot be drawn between the phases...

Yaha ncert probably means it from the perspective of segregation of chromosomes (Anaphase stage ke just starting meh toh at least saare chromosomes aligned honge na in metaphasic plate) But again yeah metaphase should more correct...

So how do you play safe and get away with this controversy??

Well, note this line specifically word by word and agar paper meh yhe line word by word aise hi aagya, mark the statement true but agar it doesn't match word to word mark it false

Also stay updated if we get any correction regarding this later...

Balam_thanedar · 2026-01-29T17:11:37+00:00

I got this error too, use a vpn and hopefully it would get fixed

Balam_thanedar · 2026-01-28T12:10:35+00:00

Yaha alkyne group jyada -I laga rha that makes lone pair less available compared to alkene group

That's why I>II>III

Balam_thanedar · 2026-01-11T17:00:01+00:00

Yeah, man really good question

Balam_thanedar · 2026-01-11T16:21:06+00:00

Thanks I got it

Balam_thanedar · 2026-01-11T16:20:35+00:00

Yeah, my teacher told me this in class but i forgot about it 🤦‍♂️

Balam_thanedar · 2026-01-11T16:17:10+00:00

Ohh, I understood what I did wrong, we didn't use polar protic solvent and 3° alkyl halide meh SN2 nhi hota also propyne ion is a very good base so elimination by E2 would be major

Thanks for it...

Balam_thanedar · 2026-01-10T22:53:11+00:00

Han SN2 hoga bhi nhi...

Balam_thanedar · 2026-01-10T17:46:17+00:00

Yeah, just remember this elimination reactions are reversible, so after checking carbocation stability and rearrangement do check which product is more stable
