Question

In sn1 reaction the first step involves the formation of

Answer 1

SN1 is a 2 step mechanism. The first step involves the breaking of the C-X bond to form a carbocation intermediate, while the second step involves the attack of nucleophile on carbocation.

Answer 2

In the sn1 reaction, the first step involves the formation of a carbocation.

• Sn1 reaction means substitution nucleophilic unimolecular reaction.
• The first step of the reaction involves the breakage of the C-X bond to form a carbocation.
• This is the slowest as well as the rate-determining step.
• The carbocation thus formed has sp² hybridization and trigonal planar geometry.
• So the approaching nucleophile can attack the carbocation from both sides with equal probability.
• This leads to the formation of enantiomeric products.
