methanol reacts with Na ! so the bubbles tht form r wat ?? OH is the product ? n r all metal hydrocarbons white ppt ?

When methanol reacts with Na, Sodium Methoxide is formed, which is white. The sodium fizzes and gets smaller, effervescence is also seen as H2 is given off

yes, but I don't use van dar waal. in the book it says van dar waal means london and permanent dipole-dipole

and from jan 12 er:
This candidate correctly identifies the main intermolecular force involved and the factor
which determines the magnitude of the force in these examples. Strictly speaking, van
der Waals forces is a general term that encompasses London forces and permanent dipole
interactions

Can someone please tell me everything what we have to know about London Forces, Instantaneous Dipoles and Induced Dipoles?

Basically, London Forces are the intermolecular forces that are the most common. They result from the uneven distribution of electrons, which forms a temporary dipole. This temporary dipole, then causes inducing or fleeting dipoles in the neighbouring molecules.
