  • What causes water molecules to have a bent shape?
    Water molecules have a bent shape due to two lone pairs on the oxygen atom, which repel the hydrogen atoms and create a bond angle less than 109.5°.
  • Which statement describes a molecule that has a trigonal pyramidal molecular shape?
    A molecule with a trigonal pyramidal shape has four electron groups: three bonding pairs and one lone pair on the central atom.
  • What is the molecular geometry of CCl4?
    CCl4 has a tetrahedral molecular geometry.
  • What shape does the molecule BF3 have?
    BF3 has a trigonal planar molecular geometry.
  • Which molecule does not have an angular shape?
    CO2 does not have an angular shape; it is linear.
  • What is the shape of a water molecule?
    A water molecule has a bent (angular) shape.
  • What is the shape of the 2p orbitals?
    The 2p orbitals have a dumbbell shape.
  • What molecular shape does the compound CCl4 have?
    CCl4 has a tetrahedral molecular shape.
  • Why is water a bent molecule and not linear?
    Water is bent because the two lone pairs on oxygen repel the hydrogen atoms, resulting in a bent geometry.
  • What shape would you expect for XeF4?
    XeF4 has a square planar molecular geometry.
  • What is the shape of an ammonia molecule?
    Ammonia (NH3) has a trigonal pyramidal shape.
  • Which molecule has the shape of a completed tetrahedron?
    Methane (CH4) has the shape of a completed tetrahedron.
  • What is the molecular geometry of a molecule with 4 outer atoms and 1 lone pair on the central atom?
    The molecular geometry is seesaw.
  • How many atoms are in a tetrahedral molecule?
    A tetrahedral molecule typically has five atoms: one central atom and four surrounding atoms.
  • What is the geometry of the BF3 molecule?
    BF3 has a trigonal planar geometry.
  • How many electron domains does carbon dioxide have?
    Carbon dioxide has two electron domains around the central atom.
  • What shape would you expect the compound hydrogen fluoride to have?
    Hydrogen fluoride (HF) is linear.
  • What is the molecular geometry for germanium disulfide?
    Germanium disulfide (GeS2) has a linear molecular geometry.
  • What is the molecular geometry of a molecule with 5 outer atoms and 1 lone pair on the central atom?

  • What is the shape of the water molecule?
    The water molecule has a bent (angular) shape.
  • What is the molecular geometry of NH4+?
    NH4+ has a tetrahedral molecular geometry.
  • What shape would you expect CH3Cl to have?
    CH3Cl has a tetrahedral molecular geometry.
  • Why do lone pairs impact the shape of a molecule?
    Lone pairs occupy more space than bonding pairs, causing greater repulsion and altering bond angles, which changes the molecular shape.
  • What is the shape of a boron trifluoride molecule?
    Boron trifluoride (BF3) has a trigonal planar shape.
  • What is the molecular shape of a CCl4 molecule?
    CCl4 has a tetrahedral molecular shape.
