IISER Aptitude test | 2017 Detailed solution | Chemistry

Hello everyone,
In this video we will solve the iiser aptitude test 2017 question paper.

[@parthkumar2058]

19:17 In Q20, the question is asking for geometry of [SnCl3]- and not shape - so shouldn’t the answer be tetrahedral? (Since shape does not consider position of lp but geometry does) I have seen a similar question elsewhere - I marked shape when geometry was asked and got it wrong - so just wanted to check if the answer should be (D) tetrahedral then, and not (C) trigonal pyramidal

[@MANPREETYADAV]

Yeah you are right Actually that is tetrahedral Trigonal pyrimidal is shape. Answer of 20 - is D (i.e tetrahedral) Geometry includes the lone pair also, but shape doesn't includes the lone pair. Thank you

[@theincredible9183]

😢😮😮😅😅😊tx 0:42

[@schrodingercattos]

distorted tetradehral hai toh trigonal pyramidal geometry hogi since not all bond angles are equal to 109.5

Its great work from you Manpreet. You are helping these students for an exam which all pioneers won't help much. From 2020 for my IAT, you were the guide to even send applications. Now I just got your notification. Keep it up

[@MANPREETYADAV]

Thank you so much It meant a lot to me

[@rashmisagar445]

Thanks bhaiya. Please opload more pyq solution of chemistry. Your explanation easily understandable.. 🙏🙏

[@mridulassv9652]

Thank you so much sir for this detailed solution video

[@studyphile231]

Bhaiyya !! Very very helpful!! Can you bring up other pyqs also, before this year's exam!

[@actorrup6978]

Sir after 2 years you uploaded video.

[@vashusingh5608]

Need more such video for physics and chem

[@nidhithakur5479]

THE MOST HOLLISTIC AND DETAILED IAT SOLN VIDEO IVE COME ACROSS THAT CLARIFIED ALL MY "WHAT IF THE Q WAS MODIFIED LIKE THIS" TOOOO SCREAMING IN CAPS CUZ IM GRATEFUL, THANK YOUU

[@Padhlebhen100]

Bhaiya plz bring such videos for physics and maths also all the years

[@shalinigovindaraj1395]

sir one doubt . in 17th question, in iii) undergoes resonance right? then electron donating will be less in the iii) and in i) due to no resonance it can easily donate electrons right? we know that more electron pair donating will be more basicity right? is this statement is correct ?

[@himasri7378]

Brother can you make other pyqs of chem too for students attempting exam this year. This would me very helpful 🙏🏻🙏🏻

[@helloyt420]

Is q17 correct? Because in 3rd option, even after it becomes CA it is anti aromatic.

[@GWanonymous]

Thanks

[@manishneekhra4583]

Bhaiya last question mein apne initial pressure jyada liya h final se isliye isothermal ka work jyada ho rha h lekin agar final pressure jyada le intial se to phir adiabatic ka work jyada ayega ??

[@GWanonymous]

Bhaiya thoda or detail me btaye ha, jisko concept ata hoga uska revision hojye ga or jisko nhi ata hoga usko concept pata chal jaye ga Like Questions no. 26 me. Apne option a q nhi ho skta ye nhi btaya And Why option b is more acidic than options D and C Thank

[@shalinigovindaraj1395]

sir at 45:08 how did you apply molarity ×molarmass as mass of solute? and molarity =moles of solute /volume of solution (in L) right? there is no volume of solution. if you substitute as 1 as volume of solution, in order to convert that into ml ,10^3 should be there right?

[@bccsteamer7496]

Same prob with me

[@bijimol9987]

Whats the safe score to get into isser out of 240 marks

[@yash7814]

Hello Bhaiya, what's the safe score to get into IISER out of 240 marks (IAT)? I will be giving IAT exam on 17 June. Please do let me know....

Sir please make a vedio on another year paper s

[@ujjwalsingh9017]

17th mai apney galat explanation dea hai, 1st waley mai dusre nitrogen ki electron density usper arhi through resonance to 1st wala sbse jyada basic hai, pahla ap lone pair ki availability check karoey to 1st mai sbse jyada electron density ayegi

Bro can you make a video for nest preparation

[@user-fr3ci9md6m]

Sir in q16 why not c is answer, removal of other alpha H is also not possible right?

[@MANPREETYADAV]

In option 3rd the compound is an active methylene compound so, the hydrogen present on alpha carbon between the two carbonyl group. Become highly acidic and can be easily abstract by base.

[@nocturnal3431]

​@@MANPREETYADAV but in Q16 "not be abstract " is mentioned .. can u reply me plz

[@shankhashuvrachattopadhyay5557]

1st question, 3rd option ka vi to active position chor ke baki 2 alpha H abstracted nehi ho raha hain

[@biharwale3612]

Ha...lekin wo v to alpha position pe hi hai na

Mil gya kya bhaiya?

[@anandrbabu6472]

If you are confused about how to prepare, it's nothing different. If you prepare for either neet or jee, you can easily be in the rank list with your core subjects. To me it was PCB, every mark in maths was an extra.

[@sayhitodevil9781]

Level of questions are very good in chemistry compared to neet and jee main

[@NavSci]

@@sayhitodevil9781 exactly , I am looking for someone with this opinion because I can find physics doable , heck even maths is doable when compared to jee math but chemistry is excellently hard sometimes ! Everywhere I go they say chemistry and biology is the easiest but i dont agree

in question 26 , you took mass of solute as 3M whereas it is clearly written in the question that the mass of solution is 3M.
