Molecular Interactions Flashcards
1
Q
Buffer
A
Resist changes in pH and enable a controlled environment
2
Q
Ångström
A
10−10 m or 0.1 nm
3
Q
Length of a hydrogen bond (O-H ¦¦¦¦¦ O)
A
2.8Å
4
Q
Energy of a hydrogen bond
A
12-30 kJ/mol
5
Q
Van der Waals interactions
A
Weak attractive force with a permanent dipole or a fluctuating and asymmetric electric charge. Binding is additive and so significant strength in high quantities
6
Q
Length of Van der Waals interactions
A
3-4Å
7
Q
Energy of Van der Waals interactions
A
1-4 kJ/mol
