Chapter 2: 2.35 (page 83)

Label the Lewis acid and base. Use curved arrow notation to show the movement of electron pairs.

Short Answer

Expert verified
  • The Lewis acids are electron-deficient species (electrophiles) that have empty orbitals.
  • The Lewis bases have properties contrasting to Lewis acids.

Step by step solution

01

Lewis acid and Lewis base

  • The Lewis acids are electron-deficient species (electrophiles) that have empty orbitals.
  • The Lewis bases have properties contrasting to Lewis acids.
02

Formation of the product

The H3O+molecule becomes a Lewis base by releasing a proton.

The CH3CH2COCH2CH3is a Lewis acid due to the presence of the carbonyl group (CO).

In this molecule, oxygen attracts the proton from the hydronium ion and thus, enhances the Lewis acidity or electrophilicity of the carbonyl carbon.

Therefore, CH3CH2COCH2CH3 accepts electrons at the carbonyl carbon from the water molecule (Lewis base).
