Verbs which do not take indirect object pronouns

I have a book with exercises of the type:

My uncle sent a book to my sister.

Which should be transformed as:

My uncle sent my sister a book.

There are some which do not seem to work well:

Our teacher explained physics to us.
Our teacher explained us physics.

Or:

Could you suggest a good book to me. Could you suggest me a good book.

I can't find a rule for when this is incorrect. Or, if not a rule, at least a list of verbs which have this property.
