Answer:
a hydrogen bond between the hydrogen of water and the nitrogen of the amine
a hydrogen bond between the oxygen of water and a hydrogen from the -NH2 group
Explanation:
A hydrogen bond is formed between molecules in which hydrogen is bonded to a highly electronegative element.
In amines, hydrogen is bonded to nitrogen while in water, hydrogen is bonded to oxygen. Both are highly electronegative elements hence hydrogen bonding is possible between amines and water.
This hydrogen bond may involve;
The hydrogen of water and the nitrogen of the amine
Or
The oxygen of water and a hydrogen from the -NH2 group
The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is :
- Reducing Atmosphere Hypothesis
<h3>Reducing atmosphere</h3>
Reducing atmosphere hypothesis states that a reducing atmosphere is a condition whereby the atmosphere has an abundance of negative charges which leads to reducing reaction by the additon of electrons to compounds.
The addition of electrons to the compounds leads to the formation of complex organic molecules. some examples of reducing gases are :
- Hydrogen and
- Carbon monoxide
Hence we can conclude that The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is : Reducing Atmosphere Hypothesis.

The answer is D, pH greater than 7. This is because when you make a solution of potassium hydroxide, it leads to an excess of hydroxide ions in the water. Since the concentration of hydroxide ions is greater than that of protons, it causes the water to be basic. The basic range on the pH scale is always greater than 7.
