Semster 2 Exam 1

Question 0

SN1

Answer 0

• Retention & inversion of stereochemistry.
• Unimolecular (substrate)
• 3°>2°>1°

Big barrier: carbonation stability

Question 1

SN2

Answer 1

• Inversion of stereochemistry
• bimolecular: depends on nuc & substrate->(alkyl halides, 1°>2°>3°

Big barrier: steric hindrance. Less bulky=faster attack

Question 2

Polar protic solvent

Answer 2

A polar bond caused by a partially positive site and negative site.

The protic comes from having a partial positive H+ from hydrogen bonding

Question 3

hydrohalogenation

Answer 3

halogen attacks the carbocation

Question 4

hydration

Answer 4

water attacks the carbocation (adds water)
