(a) NaOC2H5/CH3I

(b) H3O+/Heat ,and

(c) LDA/CH3I.

Step by step solution

01

  Acidic hydrogens in ketones

The alpha hydrogens in ketones are acidic in nature. The acidic protons will be removed in reaction with a strong base, and a carbanion intermediate will be formed. This carbanion intermediate on reaction with an alkyl halide forms a new C-C bond.

The given reaction is,

The given equation

02

Reagents

The reagents used in the reaction are,

The given chemical reaction
