The chemical bond is determined by its overall shape of
the molecule, the angles made by the lines joining the nuclei of the atoms in
the molecule. The bond angles together with the bond lengths accurately define
the shape and size of the molecule.
The answer is C, Pb 2+(aq) + CO3(aq) PBCO3(s)
+molecule size +steepness of the concentration gradient +temperature + steepness of the electric gradient +steepness
Answer: Bromide is many orders of magnitude better than fluoride in leaving group ability
Explanation:
As Size of an atom Increases, the Basicity Decreases this is because if we move downwards from the top of the periodic table to the bottom of the periodic table, the size of an atom increases. As size increases, basicity will decrease, meaning the element will be less likely to act as a base implying that the element will be less likely to share its electrons.
in the same vein. With an increase in size, basicity decreases, making the ability of the leaving group to leave increase to increase . This can be seen in the halogens going down the group from
F--- worst
Cl----fair
Br ----good
I-----excellent
with fluorine having the worst ability to leave than Bromine which is better in terms of the leaving group ability.
I think B
