Question 1

what does bimolecular mechanism

Answer 1

a mechanism in which two species are reacting in the rate determining step

Question 2

in transition state the sign goes

Answer 2

on the outside

Question 3

in Sn2 what happens after the transition state

Answer 3

the arrangements of the groups that remain attached to the central atom has been inverted

Question 4

in Sn2 the optical activity of the product are reactant would be

Answer 4

opposite to each other (because of the inversion) so if the reactant is laevoratatory then the product is dextrorotatory

Question 5

how can we find out if the mechanism that occurred is Sn2

Answer 5

by seeing if the optical activity of the product and the reactant are opposite to each other

Question 6

what is unimolecular mechanism

Answer 6

a mechanism in which only one species is reacting in the rate-determining step

Question 7

why is a racemic solution formed during Sn1

Answer 7

because it occurs in two steps where the first step forms is carbocation with a planar shape, which means when the negative OH comes to attack it has a 50% chance to attack on each side so two enantiomers with the same ratio form making a racemic solution

Question 8

how can we find out if the reaction has occurred through Sn1

Answer 8

by measuring the optical activity of the product and reactant where if the reactant has optical activity and the product doesn’t that means its Sn1
