Question

Question 6 (1 point) Which of the following can be prepared by acetoacetic ester synthesis? CO, 1

Answer 1

6)From the following compounds option 3 and 4 can be synthesized from acetoacetic ester

7) The acidic order depend on the stability of conjugate base . Stable conjugate base more acidic .So most acidic will be trifluroacetic acid next trichloro acetic acid

So order will be 2 >1 >4 >3

8) Numbering will be from functional group

So IUPAC name will be 2- Ethylpentatonic acid

9) This is an example of Grignard reaction in which Ethyl group will attack on the carbony carbon and then OMe group will remove

So option B is correct

10) LiAlD4 is a reducing agent which reduced cyclic ester to alcohol

So option A will be correct
