The correct representation is attached with the explanation.
Explanation:
In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
Answer:
Option-C
Explanation:
The sugar alcohols are the carbohydrates which are neither considered sugars nor alcohols but they partially resemble the structure of both of these sugars and alcohol.
The sugar alcohols are naturally present in the vegetables and fruits but they are also artificially synthesised like xylitol, lactitol, mannitol and others.
They are considered the alternative from of sugar but they provide less energy as compared to carbohydrates like they provide about 0-3 kcal per gram whereas sugar provides 4 kcal per gram.
This difference is due to the reason that they are not completely absorbed by the human body and also they are incompletely metabolized therefore provide less energy.
Thus, Option-C is the correct answer.
