Formic acid has the chemical formula HCOOH. It is a colorlessliquid that has a density of 1.220 g/mL. (a) The carbonatom in formic acid is bound to one H and both O’s. Drawthe Lewis structure for formic acid, showing resonance ifpresent. (b) Formic acid can react with NaOH in aqueoussolution to produce the formate ion, HCOO-. Write thebalanced chemical equation for this reaction. (c) Draw theLewis structure of the formate ion, showing resonance ifpresent. (d) How many milliliters of a 0.100 M solution ofNaOH would it take to completely react with 0.785 mL offormic acid?
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
