How many bonds does CH3OH have?from geometryofmolecules.com
While drawing the Lewis structure for CH3OH, you will notice that the Carbon atom will have three bonds with three hydrogen atoms and one bond with the Hydroxyl Group.
How many valence electrons are in CH3OH?from geometryofmolecules.com
Thus the total number of valence electrons in CH3OH ( Methanol) is 14.
How to determine methanol concentration?from pubchem.ncbi.nlm.nih.gov
Two sampling methods for reliable determination of methanol concentration were studied. Methanol vapor stored in glass container was found to be decomposed on the glass surface. The decomposition increased as the surface area of the glass container was extended. The proportion of the decomposition in the glass container was relatively high, especially when the concentration of methanol vapor was low. Therefore, a reliable determination by the above sampling method was impossible. In the solid sorbent sampling by silica gel, the collected methanol was also decomposed, but the decomposed amount was negligibly small compared to the collected methanol when the amount of methanol was more than 0.1 microliter of the liquid methanol. It could be concluded from the foregoing findings that the determination of methanol concentration by this method is reliable.
