All rights reserved. What is the molecular geometry of H2CrO4? Depending on how many of the clouds are lone pairs, the molecular geometry will be tetrahedral (no lone pairs), trigonal pyramidal (one lone pair), or bent (two lone pairs). The three electron pairs and the larger repulsive force between the lone pair and three bond pairs is responsible for this shape (trigonal pyramid) of the molecule. Select one: a. PCl_3 \\b. During such chemical bonding, an imbalance in the energy levels is created, and to attain a balance in the energy levels, the orbitals combine, which results in a hybrid orbital. Post a Question. Yes. a) In H3PO4, P has a tetrahedral molecular geometry and is sp3 hybridized. [23][24] There is a second smaller eutectic depression at a concentration of 94.75% which will not freeze down to 23.5C.
