NEET UG 2026 Re-Exam 21 June Solutions Part 10 Q46–Q50 Chemistry | T.I.M.E. Salem

[00:00:00]Hi children, welcome back to chemistry class. In the re-NEET 2026 order chemistry part, that is for paper code 50 video solution of our problem.

[00:00:10]Number of the part of the 46 and 90 with other 46 equation number of the benzene number of the acyl chloride product in the presence of aluminum chloride.

[00:00:20]Number of the reaction and then the Friedel-Crafts acylation. Above P and Q are getting P number of the product Q number of the product acyl chloride product reaction of the product number of the number of the P and Q number of the product sodium benzoate uh CHCl3 number of the product other product number of the product number of the product number of the product carboxylic acid product in the CHCl3 CHCl3 reacts with air in the presence of light in the product we'll get a gas called phosgene. Phosgene is a poisonous gas. Above number of the product option number of the product option number of the P number of the product number of the carboxylic acid product other than acidification number of the product sodium benzoate number of the product carboxylic acid product right other than number of the product number of the product Q that is called the another CHCl3 other poisonous gas product number of the air light presence of air and the light that is called the phosgene. Above number of the option number of the third one right So 47th question statement number of the other statement So in the in the other Fe is your metal oxalate other than that in the other CO oxalic acid number of the product COO- COO- It is a symmetrical in the other dentition in the other dentition symmetrical bidentate Okay. So above in the chiral in the other chiral or in the other number of the So this is your M A A 3 of the structure Fe OX3 in the other So in the other in the other optically active So it is chiral.

[00:02:01]So, mirror images are non-superimposable.

[00:02:04]Okay, trans M A2 B2 or M A2 B2 If you have monodentate and you have trans position and trans You don't have mirror image and superimposable. So, you don't have statement two. Trans are optically inactive. You have cis and optically active. Right?

[00:02:26]Okay.

[00:02:28]So, second one chiral and so you don't have it. So, symmetric present. So, second statement is wrong. First statement correct.

[00:02:36]Second statement wrong. So, statement one is correct and statement two is incorrect. So, that is your option three. Right?

[00:02:49]Moving to the question number 48. So, carbocation stabilized by another another interaction product.

[00:02:57]And it is it happens through what?

[00:03:00]Hyperconjugation and resonance.

[00:03:01]Resonance occurs with sigma bond. You have filled sigma orbitals. And um hyperconjugation by orbitals.

[00:03:10]Right? Filled sigma and filled by orbital. Right? Filled sigma and filled by orbital. That is option So, 49 native potash alum. You have potash alum and K2SO4 Al2SO4 3.24 H2O.

[00:03:34]Potassium and sulfate ratio You have two potassium and you have two potassium ion.

[00:03:41]SO4 2- ratio. You have two potassium.

[00:03:46]You have potassium sulfate. You have four. You have sulfate. You have four. So, 1/2. Both will be in the ratio of 1:2.

[00:03:56]That is option one. But again, 50th question in a particular correct statement about types of proteins peptide and protein any correct on a statement made it so that we related structures beta related sheet structures in a number of the NCERT biomolecules in the number of the question now.

[00:04:18]So, that is option three.
