for question 27 i am not sure either, but B dont seem to be stable anion when donating acid..!Hi, Im having trouble reasoning and accepting the answers for questions 27. 33. 38. and 39. from this past years paper :
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w08_qp_1.pdf
Can anyone please clarify the answers (i.e. give reasons) for the questions above?
The answers are C, D, D, B.
For 27. why is the answer not B?
For 33. Why is the answer not B?
Thank you! God bless!
for 33, activation only govern the rate...because enthaply change can be low yet HIGH activation energy!
for 38, only 1 is inflammable enuf! thou 2 seems inflammable yet the R group of RBr is big !
and for 39 i dont know how to answer
