Does the octet rule where atoms want a full eight valence electrons in their outer shell only apply to carbon, nitrogen, oxygen, fluorine, chlorine, bromine, iodine, and hydrogen? Explain. Why is fluorine important? Which compound is an exception to the octet rule?
Why is carbon 14 less stable than carbon 12? Why is an ethyl radical more stable than a methyl radical? Explain why tertiary carbocations and radicals are the most stable? Which do you predict will be more stable: bromine-79 or bromine-80? Explain. ...
Life on Earth is known to rarely make fluorinated carbon compounds, as compared to other halocarbons. We quantify this rarity, based on our exhaustive natural products database curated from available literature. We build on explanations for the scarcity of fluorine chemistry in life on Earth, ...
The rods will then tend to pack together a bit like long thin pencils in a box." So, what this means is that even if the C-F bond is very strong and fluorine very resistant to polarization, the fact that PTFE is so dense and the polymer strands organized so tightly and regularly ens...
Adelhelm LubriCoat NA is headed up by Adam Berres (left) and Dan Drayna (right). For more, visit their website.All Teflon™ coating varieties are “fluoropolymers,” which are fluorocarbon-based polymers with multiple carbon-fluorine bonds. This classification means that they possess a number...
The truth may lie somewhere in between. The main theory that explains absorption is that thecarbon dioxide reacts with the water molecules in the air to create a compound called oxalate. This compound in turn combines with the protein fluorine in the hemoglobin so that the red blood cells can...
The presence of the C-H bond in aldehydes can be converted into a C-OH bond (alcohol) during oxidation. 4. Bond Strength in Ketones: - In ketones, the carbonyl carbon is bonded to two other carbon atoms (C-C bonds). These carbon-carbon bonds are relatively strong and require more ...
SF(6) is kinetically an inert compound or is stable in nature. This is on account of the reason that six fluorine atoms around the central sulphur atom cause lot of steric hindrance to the attacking reagent. Therefore, SF(6) does not readily take part in
has more protons and thus the electrons will be closer to the fluorine atom than the carbon atom. This is an unequal sharing of electrons between two bonded atoms and such bonds are known as polar bonds. The bond between the nitrogen and the hydrogen atoms are also similar in case of ammo...
20oC at 1 atmosphere pressure (Earth, sea-level). This is a warmer temperature range than the other solvents that are likely to be universally abundant, apart from water. However fluorine itself is not a very abundant element and HF, in the presence of water, will turn into hydrofluoric ...
