Many of these characteristics have to do with whether a fat is "saturated" or "unsaturated." Saturated vs. Unsaturated If you look at palmitic acid and stearic acid chains, you can see that the carbon chains are completely and evenly filled with hydrogen atoms. In other words, the chains...
Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...
Alkadienes must have 5 carbon atoms and at least two double bonds. 1. 1,3-Pentadiene: - Structure: CH₂=CH-CH=CH-CH₃2. 1,4-Pentadiene: - Structure: CH₂=CH-CH₂-CH=CH₂ Total alkadienes = 2 Step 5: Calculate the Total Number of CompoundsNow, we can sum up the ...
