Answer:
(a) Formation of the carbocation is the rate-determining step (RDS)
(c) Reactions at chiral carbons proceed with inversion of stereochemistry
Explanation:
SN1 reactions arenucleophilic substitution reactions in which the rate determining step is unimolecular.
The formation of a carbocation is the rate determining step. This depends on the electrophilicity of the leaving group. Thus the SN1 reaction mechanisms is dependent on the electrophile and not the nucleophile.
Polar and acidic solvents which can assist in the formation of the carbocation speeds up the rate determining step.
If the formation of carbocation occurs at a chiral center, both retention and inversion of stereochemistry are likely to occur.
Therefore, the correct options are A and C.
Answer:
The Brain
Explanation:
The brain is responsible for managing the functions of all other organs.
Answer:
0.151 mol
Explanation:
molar mass of KNO3 = (39.1 + 14 + 3×16) g/mol = 101.1 g/mol
number of moles = mass/molar mass
n = m/M = 15.3 g/(101.1 g/mol) = 0.151 mol
Answer:
#1 is protons electrons and neutrons
their respective parts are center, positive ,and no charge
#2 is positive charge, chemical properties
#3 is the number of protons, characteristics, same
#4 is atomic mass, average atomic mass
#5 is mass number, nucleus
