Which of these two possible hydrogen-bonding interactions is more likely to occur? (Hint: Consider resonance structures for formamide.) There are three formamide molecules with two labeled hydrogen-bonding interactions. The formamide molecule has the following structure: HCNH2 with an O atom double-bonded to the carbon atom. The O atom has two lone pairs, whereas the N atom has one lone pair. The hydrogen-bonding interaction between an H atom bonded to the N atom of the first molecule and the O atom of the second molecule is labeled as number 1. The hydrogen-bonding interaction between an H atom bonded to the N atom of the second molecule and the N atom of the third molecule is labeled as number 2.'
