Question

based on the molecules below, indicate whether each of the following statements is true or false. the oxygen and hydrogen involved in the labeled hydrogen bond are sharing two electrons, one from each atom. choose the oxygen and hydrogen involved in the labeled hydrogen bond are attracted to each other because they have opposite partial charges. choose the oxygen and hydrogen involved in the labeled hydrogen bond have exchanged electrons. choose all of the hydrogens in the molecules shown are bound to another atom with a hydrogen bond. choose

Explanation:

1. First Statement:

A hydrogen bond is an intermolecular force, not a covalent bond (where electrons are shared). So the oxygen and hydrogen in a hydrogen bond don't share electrons. Thus, the statement is false.

In a hydrogen bond, the hydrogen (attached to an electronegative atom like N/O/F) has a partial positive charge, and the electronegative atom (O here) has a partial negative charge. Opposite partial charges attract, so this statement is true.

Hydrogen bonds involve electrostatic attraction due to partial charges, not electron exchange (which is for ionic bonds or redox). So the oxygen and hydrogen in a hydrogen bond don't exchange electrons. The statement is false.

Answer:

False

2. Second Statement:
