  1. here is one correction in your first line- g is used when the complex is octahedral and it has no relation with even or odd figure.... try a book group theory by sutton ..
  2. hi guys .... i want some very useful information from that weblink from which old content was removed and new data is uploaded ......... is there any way to get that old data????? i will be highly thankful to all those who guys who will help me :-):-) ...........
  3. hello......if anybody how molecule rotate plane of polarised light then please let me know also ........ upto my knowledge there are certain kind of vibrations in a molecule which cancel the vibrations of light in all direction leaving one ........ but i wanna know how these vibrations get cancel out.???? i need any sort of hint or ans. (which is banned in this forum).......
  4. thanks for your concern ......... you said that we can calculate optical rotation of single molecule but its a very hard job ....... can you please suggest me any method 4 finding optical rotation of single molecule ????
  5. good evening ...... yesterday when i was i reading a book of stereochemistry by Eliel few ques. ( may be foolish ) came to my mind ......... is their any relation between degree of optical rotation of a molecule and its various unstable conformations ( not configuration) ?????........how can we say that these particular molecule rotate plane polarized light to any specific degrees ????? we normally calculate optical rotation of a solution i.e a collection of molecules ...... why don't we look for optical rotation of a single molecule ?????? if the degree of optical rotation is related with conformations of molecule then there may be possibility that in a single solution we have different species which can have different optical rotation ........ is there any mathematical equation which can relate degree of optical rotation with dihedral angle of molecule ?????
  6. May be this will help you .......... look for the both thermodynamically and kinetically derived product ........... in A there is a formation of allylic intermediate which is more stable than primary carbocation as in case of B .......... so A intermediate will form at a faster rate than carbocation ........ results in formation of 1,2 addition product in major amount ...........so 1,2 product is kinetically favored ........ now look on the final product ......... 1,4 product is more stable than 1,2 as 1,4 product is more substituted alkene so thermodynamically favored ......... so as soon as 1,2 product form there is enough collision energy ( even at room temp. ) to pass over the energy barrier from 1,2 product to 1,4 product........
  7. hi to all . i need urgent help . i am using windows vista sp1 and windows 7 on a same pc . windows 7 is running awesome but there came problem in windows vista . i was playing a game and suddenly screen rotates by 90 degree . may be there is some problem in windows or in monitor driver . may be its in vista because windows 7 is running fine . try to resolve this problem . thank you ....
  8. Sounds pretty interesting; I'll give it a go. :)
