NUCLEOPHILIC SUBSTITUTION REACTION

The type of reaction shown is called

• Addition reaction

• Nucleophilic reaction

• Electrophilic reaction

• Substitution reaction

S_N1 stands for

• Unimolecular nucleophilic substitution

• Bimolecular nucleophilic substitution

S_N2 stands for

• Bimolecular nucleophilic substitution

• Unimolecular nucleophilic substitution

S_N1 mechanism favors

• 3° haloalkane

• 1° haloalkane

S_N2 mechanism favors

• methyl halide

• 3° haloalkane

reactivity of haloalkanes towards S_N2 mechanism

• 3° > 2° > 1°

• 3° < 2° < 1°

The reaction mechanism shown below is

• S_N1

• S_N2

Which of these has only one transition state?

• SN1

• SN2

Which of these is a one step reaction?

• SN1

• SN2

Reaction below shows S_N1 reaction. Which statement is FALSE?

• Unimolecular collision

• OH^- is a nucleophile

• Two step mechanism

• Rate of reaction depends on both concentration of haloalkanes(RX) & nucleophile of H₂O

Answer explanation

Since its S_N1 reaction mechanism, the rate of reaction only depends on concentration of haloalkanes (RX)
