In chemistry, the Linear molecular geometry describes the arrangement of three or more atoms placed at an expected bond angle of 180º. Linear organic molecules, e.g. acetylene, are often described by invoking sp orbital hybridization for the carbon centers. Many linear molecules exist, prominent examples include CO₂, HCN, and xenon difluoride. Linear anions include N₃⁻ and SCN⁻. Linear cations include NO₂⁺.^[1]
