Sp Hybridization in Alkynes: Exploring Triple Bonds
In alkynes, such as acetylene (C₂H₂), carbon atoms undergo sp hybridization. This involves the mixing of one 2s orbital and one 2p orbital, forming two sp hybrid orbitals. These orbitals align in a linear arrangement with a bond angle of...

Sp² Hybridization in Ethene: The Secret of Double Bonds
Hybridization Process: Carbon atoms undergo sp² hybridization, mixing one 2s and two 2p orbitals to form three sp² hybrid orbitals arranged in a trigonal planar geometry (120° bond angles). Bond Formation: Two sp² orbitals form sigma (σ)...

VSEPR Theory - lone electron pair influence
Bond Angle Distortion: Lone pairs reduce bond angles between bonding pairs. For example, in a molecule like NH₃ (ammonia), the ideal tetrahedral angle of 109.5° is compressed to around 107° due to the presence of a lone pair on nitrogen....
