Organic Chem

Question 1

Specific Rotation

Answer 1

Standardized rotation that takes into account concentration and sample cell length.

[a] = a_observed / (c x l)

c = concentration

l = path length

[a] = specific roation

Question 2

Process of SN1 reactions and relative reactivity

Answer 2

SN1 reactions are a 2 step reaction: (1) loss of leaving group and carbocation formation, (2) nucleophilic attack

Because a carbocation is formed, tertiary molecules are the most reactive

Question 3

What are Z and E alkenes

Answer 3

Z = cis

E = Trans

Question 4

Zwitterion

Answer 4

Doubly charged ion in which the charges cancel each other out

Question 5

Converting wedge/ dash diagrams to chair diagrams for cyclic compounds

Answer 5

wedges = up on the chair diagram

dashes = down on the chair diagram

Question 6

Ketone + Secondary Amine => ?

Answer 6

Enamine

Question 7

ketone/ aldehyde + primary amine => ?

Answer 7

Imine

Nitrogen analog to a ketone, N double-bonded to carbon and an R group
