Scl6 is non-polar because it has 6 bonding pairs and no lone pairs, giving it an octahedral shape. When you draw the vectors, you can see that the resultant is 0, making it nonpolar. Scl4 on the other hand is polar because it has 4 bonding pairs and one lone pair, giving it a trigonal pyrimidal shape. When you draw vectors for this molecule you can see that the resultant displacement is <0, and therefore it is polar.
How do lone pairs around the central atom affect the polarity of the molecule?
The active site is part of an enzyme where substrates bind and undergo a chemical reaction.
It shows the shape of the molecule
Because they push the bonding pairs down. For example in a water molecule, it has 2 lone pairs which push the 2 bonding pairs down to form a V-shaped molecule. Hope this helps
As the CCl4 molecule has a regular tetrahedral shape the hybridisation is sp3

Water is not a linear molecule because of the location of oxygen's electron orbits. The bonding electrons are angled and this results in the shape of the molecule.
The shape of the enzyme must match the shape of the substrate. ... Higher temperature generally causes more collisions among the molecules and therefore ... bonding within the protein molecule change and the molecule changes shape.Can cause the enzyme to change shape? If you mean What causes it to change shape, mainly it's heat.
A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule changes and the molecule changes shape. The new shape therefore may not be effective

C.A molecule that has a symmetrical shape will be a nonpolar molecule.

Molecular geometry is the distances and angles between the each of the different atoms in the molecule. It is essentially the shape of the molecule.Molecular structure includes the shape of the molecule, but also much more, such as its electronic structure. This includes the nature of the bonding in the molecule (such as where there are single, double or triple bonds), the polarity of the molecule (if the electrons are spread out evenly throughout the molecule or if they are concentrated in particular areas, and if so, what areas), etc.
