Q

How is a temporary dipole made in LDFs?

A

The electrons in the atom
This causes the electrons to move away from nearby atom causing a negative change
Thus a temporary dipole is induced

Q

How strong is H bonding compared to LDFs and PD-PDi?

A

Q

Why is does NOF create H bonding?

A

Because H has an electronegativity of 2.2 while NOF have a high electronegativity so the polarity is very high
