However, VSEPR theory suggests that the π bond would "need more space" due to greater electron repulsion. VSEPR predicts that formaldehyde is a trigonal planar compound, with 120 o bond angles. Trigonal planar with three atoms bonded. Allene, $\ce{H2C=C=CH2}$, has two $\ce{=CH2}$ groups perpendicular to each other. The bond angles are compressed relative tothose in a perfect trigonal bipyramid due to lone pairs spreading out more in space than bonded pairs. In this case the symmetry of the system is reflected in the Z-Matrix through the use of identical variable names for hydrogen atoms H5 - H8 and through constraining all atoms to the symmetry plane.
