    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

      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

      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

    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 ?

      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.

    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?

    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.
