    Chemistry: Post your doubts here!

    only one (the answer is B) any carbon with a double bond or two similar groups like CH2 cant be chiral. so the only one is the CH with the benzene ring attached to it.

    confusion here, please help!

    1 = 8 - 12 + 4 - C leave C there solve this way 1 = -4 + 4 - C oh :P yeah its -1! sorry
  11. G

    confusion here, please help!

    yeh my point exactly, you also get -1 if you dont use order of operation, use order you get -9 and do randomly you get +1! crazy right!
  12. G

    confusion here, please help!

    true that if you rearrange it you get +1 what if you do 1 = 8 - 12 + 4 - C so C = 8 - 12 +4 -1 =8 - 16 -1 = -9

    confusion here, please help!

    oh my bad iv written it wrong its supposed to be 1 = 8 - 12 + 4 - C
  14. G

    confusion here, please help!

    none taken...see there sometimes when you solve you may have to do it randomly or use the order of operation, for calculations, could be anything...is there any specific rule to what way we are supposed to use.

    confusion here, please help!

    if you solve this 1 = 8 - 12 + 4 - c then you either get -9 or even 1 how do we know which one to do!
