10.4 Electrophilic addition

Which statement is FALSE ?

• Electrophile is an electron deficient species
• donate a lone pair
• Positively charged species
• Attack an electron rich region

Reaction mechanism shown below is

• Substitution reaction
• Nucleophilic substitution
• Addition reaction
• Bromination reaction

Addition reaction happens for alkene because

• stable C=C double bonds
• unstable weak π bonds
• stable C-C bonds
• unstable sigma bond

Diagram shows the formation of

• 1° carbocation
• 2° carbocation
• 3° carbocation
• None of the above

Diagram shows the formation of

• 1° carbocation
• 2° carbocation
• 3° carbocation
• None of the above

Which carbocation is most stable and why?

• 1°carbocation because of strong inductive effect
• 1°carbocation because of weak inductive effect
• 3°carbocation because of weak inductive effect
• 3°carbocation because of strong inductive effect

NGSS.HS-PS1-2

Based on Markovnikov's rule, A is the major product because

• greater positive inductive effect due to 1° carbocation form
• greater positive inductive effect due to 2° carbocation form
• greater positive inductive effect due to 3° carbocation form
• None of the above

Based on Markovnikov's rule, A is the major product because

• greater positive inductive effect due to 1° carbocation form
