Homework Help: Product in a reaction

  1. May 4, 2015 #1
    1. The problem statement, all variables and given/known data
    The product formed in the reaction of SOCl2 with white phosphorus is
    1. PCl3
    2. SO2Cl2
    3. SCl2
    4. POCl3
    2. Relevant equations

    3. The attempt at a solution
    I can google that but I want to know that how can we know it intuitively or by ourselves?
    It was asked in a test and in test, internet is not available.

    There must be a way or then why it is asked in exam because there are many reactions in World ( may be infinite) and to rote memorize each of it may not be fruitful as we have to look at our retention power?

    These days I wouldn't know without checking some reference book.

    At the same time there was definitely a moment (when I learned for an inorganic chemistry exam) that I remembered many such things.

    But in reference books also so many reactions are given maybe 100 or 150 for s - block. 300- 500 for p-block. They have done the balancing , written stoichometric coefficients, reactants and products.What is a clever way to learn?

    Are the exams checking our rote memorization power by that?

    It is in ncert page 177.
  6. May 4, 2015 #5
    HaHa know that. Can you answer my post 3?
  7. May 4, 2015 #6
    For P block, s block and hydrogen only (and only) NCERT is sufficient for JEE (adv). For metallurgy, d-block, inorganic qualitative analysis (not in ncert) you need to go in deep.
  8. May 4, 2015 #7
    Do you know every reaction given in NCERT of s block and p block?
  9. May 4, 2015 #8
    I need to revise the whole s block, p block and Hydrogen after which i can claim that(which I have not recently). But this is the minimal requirement that must be fulfilled to gain a score in inorganic.

    What is a clever way of learning this reactions as I have asked in post 3 ?
    You may have read that chapters earlier also in 11th grade but the thing is of retaining.
    Some chapters we remember because of interest.
    I was also trying to revise but it seems hard.

    There is no clever way. In a week, study and revise the whole inorganic twice, (nowadays you will need more time dedicated as we don't have time). Revise, revise, revise......

    Yes and there must be some reason beta-napthtol rings a bell, I must have known what it is used for once.:redface: :oldfrown:

    So you have seen my other thread, involving β naphthol.:smile:
    I was just asking if you people know some tricks to learn inorganic chemistry the clever way to retain all.

    So I think the conclusion reached is don't give importance to these topics so much or if you have the power learn it all.( I hope epenguin will not put me in his blacklist.:rolleyes: )
    In my opinion there must be a mechanism for these reactions or the people have not discovered that?
