The partial negative charge (δ-) comes from one of the electronegative elements F, O or N. These are called H-bond acceptors. The partial positive charge (δ+) comes from an H bonded directly to one of these elements (O-H, N-H, F-H). These are called H-bond donors. Both a donor and an acceptor are needed to form an H …
