Cyanohydrins can be made from carbonyl compounds by generating CN–ions from HCN in the presence of a weak base.
In a similar reaction, –CH2CO2CH3 ions are generated from CH3CO2CH3 by strong bases. Which compound can be made from an aldehyde and CH3CO2CH3 in the presence of a strong base?
A CH3CH(OH)CO2CH3
B CH3CO2CH2CH(OH)CH3
C CH3CH2CH(OH)CH2CO2CH3
D (CH3)2C(OH)CH2CO2CH3
this question is taken from O/N 2009, paper 11/12.
I only know that A is impossible, but how about B,C,D? they only differ in the arrangement of the carbon and amount of carbon atoms.
any help is greatly appreciated, and a fast reply is needed. I'll be having a school test on Monday, and this question bothers me
