    Mam you told that higher the frequency, more easily the bond will break. If that's the case then C-C triple bond having freq. 2200 cm-1 should be weaker than C-C double bond having freq. 1650cm-1.

    Mam jitna jyada bond weak hoga uski frequency utni hi km honi chahiye na to is hisab se c-H bond ki frequency jyada h to bond utna hi strong hoga na like him metal carbonyl mai pdhte h jitna jyada metal back bonding krega Co ke sath to to C - O bond weak hoga or frequency v km hogi....

    In last question right side Numbering is something wrong, we give number with N atom; their were example is correct no need to add one new CH3 group

  • @pranjultripathi2630
    @pranjultripathi2630 5 ปีที่แล้ว

    At 34:00, Ma'am, like you said greater the frequency lower would be the strength, but in OTM, we consider greater the stretching frequency, higher the strength. Both are different?

  • @zahinsultana76
    @zahinsultana76 4 ปีที่แล้ว +1

    No.2 example of hoffler..mam you gave the numbering in left side starting from N and right side starting from C..why??

    • @zahinsultana76
      @zahinsultana76 4 ปีที่แล้ว

      Isiliye left side radical become 2• and right side 1• ..if both the numbering starting from same atom then both became same priority's radical

    Why H is abstracted from the side of e withdrawing group? The resulting radical would be unstabilised then?

    ma'am , ek baat btao aap ye 4th questions me apke saare rule fail hogye uoar se leke niche tak , phli baat oxygen bond hydrogen ke sath bana rha tha , na ki carbon pe , dusra tumne kaha delta hydrogen necessary hai bond bnaye or 4th me bana bhi rha hai , to fr nya rule laye tum double bond ko tod ke radical bana diya , hydrogen ki koi aukaat ni reh gyi , baaki sab to thik hai par ye kya tha , kuch to rule thik se apply ho 4th me 😒
