Answer:
Iodide> Bromide > chloride > flouride
Explanation:
During a nucleophilic substitution reaction, a nucleophilie replaces another in a molecule.
This process may occur via an ionic mechanism (SN1) or via a concerted mechanism (SN2).
In either case, the ease of departure of the leaving group is determined by the nature of the C-X bond. The stronger the C-X bond, the worse the leaving group will be in nucleophilic substitution. The order of strength of C-X bond is F>Cl>Br>I.
Hence, iodine displays the weakest C-X bond strength and it is thus, a very good leaving group in nucleophillic substitution while fluorine displays a very high C-X bond strength hence it is a bad leaving group in nucleophilic substitution.
Therefore, the ease of the use of halide ions as leaving groups follows the trend; Iodide> Bromide > chloride > flouride
Answer:
Chemical bond
Explanation:
Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.
C. Earth's gravitational force is stronger than the Moon's.
Since Earth has a far larger mass than the Moon, its gravitational force is also higher.
answer: A and C
Explanation:
i think its that because all you have to do is just think about it very slowey in it will just come to your head.
