Aldehydes/Ketones/Imines Flashcards
1
Q
What is common between ketone & aldehyde?
A
C=O
2
Q
Ketone
A
R-C=O-R (middle of the carbon chain)
3
Q
Aldehyde
A
R-C=O-H (end of the carbon chain)
4
Q
Explain polarity of C=O
A
C=O is polar
Polarised towards oxygen
O slight negative charge & 2 lone pairs
C slight positive charge
5
Q
Imines
A
C=N
6
Q
Explain C=N polarity
A
C=N polar
Polarised towards N
N slightly negative charge & 2 lone pairs
C slightly positive charge
