‍Structure of Ethene:

Ethene consists of two carbon atoms bonded together by a double bond.
Each carbon atom is also bonded to two hydrogen atoms.
The double bond between the carbon atoms consists of one sigma bond and one pi bond.
The molecular geometry of ethene is planar, with a bond angle of approximately 120 degrees.

Bonding in Ethene:

Ethene contains both sigma (σ) and pi (π) bonds.
Sigma bonds are formed by the overlap of atomic orbitals along the internuclear axis.
Pi bonds are formed by the overlap of adjacent p orbitals that are perpendicular to the internuclear axis.
The pi bond in ethene is weaker than the sigma bond and is responsible for its high reactivity

‍Applications of Ethene:

Production of plastics: Ethene is a key raw material in the production of polyethylene, which is used in various plastic products.
Chemical synthesis: Ethene is used in the synthesis of ethanol, ethylene oxide, ethylene glycol, and other chemicals.
Ripening of fruits: Ethene is involved in the ripening process of fruits and is used to control fruit ripening in commercial settings.
Welding and cutting: Ethene is used as a fuel gas in oxy-fuel welding and cutting processes.
Plant hormone: Ethene acts as a plant hormone and regulates various physiological processes in plants, including fruit ripening and senescence
