A hydrogen bond is Select one: a. an attractive force that usually involves a polarly-bonded hydrogen atom and another polarly-bonded atom with a partial negative charge b. a sharing of a pair of electrons between a hydrogen and an oxygen nucleus c. the loss of an electron by hydrogen to a highly electronegative atom d. a sharing of a pair of electrons between a hydrogen nucleus and either an oxygen or a nitrogen nucleus e. none of these socratic. org

answer is a) an attractive force that usually involves a polarly-bonded hydrogen atom and another polarly-bonded atom with a partial negative charge

Explanation: hydrogen bond is a special type of bonding that closely resembles an ionic bond. It involves hydrogen atom and another highly electronegative atom, this bond is due to the the attraction between the slight positive charge on the hydrogen and the slight negative charge on the pairing atom.

Note that electron is not transfered as in ionic bonding.

Molucules with hydrogen bonding between their atoms includes water, hydrogen fluoride and ammonia.
