What is the molecular shape of XeCl4?
square planar
The resulting XeCl4 molecule has a square planar molecular geometry analogous to xenon tetrafluoride.
What is the molecular geometry shape of ammonia?
trigonal pyramidal shape
The ammonia molecule has a trigonal pyramidal shape with the three hydrogen atoms and an unshared pair of electrons attached to the nitrogen atom.
What is the molecular shape and the actual shape for a molecule of ammonia?
Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
What is the molecular shape of ammonia NH3 )? * 2 points?
Is XeCl4 a polar molecule?
Owing to the symmetric arrangement of the Xe-F bonds and the non-bonding electron pairs, the net effective dipole across the whole molecule is zero. Therefore, XeF4 is a non-polar molecule (or compound) by nature.
Why is XeCl4 square planar?
Now if we follow the VSEPR theory, the net electronic repulsions has to be minimum. With this, they will acquire a stable state. In order to achieve this, the lone pairs lie in a perpendicular plane in an octahedral arrangement opposite (180 degree) from each other. Therefore, XeF4 molecular geometry is square planar.
Is ammonia a planar molecule?
The Lewis structure for ammonia looks like this… You can see the lone pair (nonbonding) of electrons directly above the nitrogen. If the central atom with no lone pair is bonded to three other atoms the molecule will have a trigonal planar shape.
Why is the shape of ammonia pyramidal?
Three of these electron pairs are used as bond pairs which leaves one lone pair of electrons. The lone pair repel more strongly than bond pairs giving tetrahedral arrangement. Since the lone pairs are invincible the shape of ammonia is trigonal pyramidal.
What is the correct molecular geometry of NH3?
trigonal pyramidal
The molecular geometry of NH 3 is called trigonal pyramidal (see Figure 9). Figure 9. Ammonia molecule.
Is NH3 trigonal pyramidal?
If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3).
