How many compounds,of the ones listed below,have hydrogen bonding? CH₃(CH₂)₂NH₂ CH₃(CH₂)₂NH(CH₂)₄CH₃ (CH₃CH₂)₂N(CH₂)₄CH₃ A) 2 B) 3 C) 1 D) 0

Question

Quizplus · Accepted Answer

Hydrogen bonding occurs when hydrogen is directly bonded to a highly electronegative atom such as nitrogen, oxygen, or fluorine. The compounds listed are difficult to interpret due to the formatting, but based on the presence of "NH" or "NHS" groups, it can be inferred that at least some of these compounds have nitrogen-hydrogen bonds, which are capable of hydrogen bonding.
