Which of the following statements related to S N1 reactions is not true? - The heterolysis of a bond between atoms which do not
bear formal charges always produces a cation and an anion - The charged carbon atom of a carbocation has a complete octet of valence shell electrons - Carbocations are Lewis acids - Nucleophiles seek centers of low electron density
The charged carbon atom of a carbocation has a complete octet of valence shell electrons
Explanation:
A charged carbon atom of a carbocation has a valence shell that is not filled, <u>that's why it acts as an electrophile (or a Lewis base)</u>. This unfilled valence shell is also the reason of the nucleophilic attack that takes place during the second step of a SN1 reaction.
The answer is B as isotopes are different versions of the same chemical element containing the same amount of protons and electrons but different amounts of neutrons.
The answer is A: When the energy transporting sediments diminishes, the sediments settle in a low-lying area; therefore, deposition always follows erosion
