Question

Be sure to answer all parts. Draw a stepwise mechanism for the following reaction. [1] LiAlH4 CH3COCI CH3CH2OH [2] H20 Part 1 out of 4 Nucleophilic substitution of H for Cl: CH3 T + AIHz H3Al-H draw structure ... i + Cr draw structure ...

Answer 1

the Hydrogen from LiAlH4 attacks on the carbonyl carbon and then forms the alkoxide ion and the undergoes rearrangement forms the aldehyde is product and the curved arrow mechanism is as follows
