A model of the organic compound allene is shown below. (a) Explain why the allene molecule is not flat. That is. explain why the CH 2 groups at opposite ends do not lie in the same plane. (b) What is the hybridization of each of the carbon atoms in allene? (c) What orbitals overlap to form the bonds between carbon atoms in allene?

  1. (a) Explain why the allene molecule is not flat. That is. explain why the CH2 groups at opposite ends do not lie in the same plane.
  2. (b) What is the hybridization of each of the carbon atoms in allene?
  3. (c) What orbitals overlap to form the bonds between carbon atoms in allene?

(a)

Interpretation Introduction

Interpretation:

The reason behind the given statement that given allene molecule is not flat has to be stated and explained.

Explanation of Solution

Analyzing molecular planarity:

The central carbon of the allene molecule possesses two un-hybridized P-orbital (two dif...

(b)

Interpretation Introduction

Interpretation:

The hybridization of each of the carbon atom in allene molecule should be determined.

Concept Introduction

Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.

Geometry of a molecule can be predicted by knowing its hybridization.

Geometry of different types of molecule with respect to the hybridizations are mentioned below,
