Refer to the two dimethylamine molecules hydrogen-bonded with water shown below. Identify the bonds made or broken and where the electrons go when they react, forming an amine, an ammonium ion, OH^–.

• A. The N–H bond in dimethylamine is broken, an O–H bond is made, and no electrons are transferred.
• B. The N–H bond in dimethylamine is broken, an O–H bond is made, and two electrons are transferred from dimethylamine to water.
• C. One O–H bond in water is broken, an N–H bond is made, and no electrons are transferred.
• D. One O–H bond in water is broken, an N–H bond is made, and two electrons are transferred from water to dimethylamine.
