Question
Which of the following molecules would show the most mtense FT-IR signal for the alkyne vibration around 2200 cm
O 1. HC CH
O 2. propyne 1-ol
O 3.2-butyne
O4. CH3CH2C=N
Os. 1,2-diphenylethyne
QUESTION 39
Why were the product alkenes removed by simple distillation in the dehydration of 2 methyl-2-butanol with 9 M H2SO4 rather than extracted with an organic scivent?
O 1. Alkenes are not very soluble in organic sotvents
O2. The dehydration is a reversible process
O3.2 Methyl 2-butanol will not react with 9 M H2S04 at room temperaturE
O4. Simple distilation ensures that only one alkene isomer is formed
O 5. None of the above
