Q. In the mechanism of the SN2 reaction, which of the following statements is true?
A.
The reaction involves a carbocation intermediate.
B.
The nucleophile attacks from the opposite side of the leaving group.
C.
The reaction rate depends only on the concentration of the nucleophile.
D.
The reaction occurs in a single step with a trigonal planar transition state.
Solution
In an SN2 reaction, the nucleophile attacks the substrate from the side opposite to the leaving group, leading to a backside attack.
Correct Answer:
B
— The nucleophile attacks from the opposite side of the leaving group.
Q. In the reaction of an alkene with HBr, what is the major product when the alkene is asymmetric?
A.
Markovnikov product
B.
Anti-Markovnikov product
C.
No reaction
D.
Polymerization
Solution
According to Markovnikov's rule, the hydrogen from HBr adds to the less substituted carbon of the alkene, leading to the formation of the Markovnikov product.
