Question 3 3pts The formula for formic acid is commonly written as HCOOH. Formic acid can lose the H bound to the oxygen atom as H+, to give the conjugate base, formate (CHO 2-). But we also know there is a double bond and this acts like a single bond (from the principles of hybridization). I quickly take you through how to draw the Lewis Structure of HCO2H (Formic or Methanoic acid) . There is a second resonance form of formate, in which the other oxygen atom has the In this case, there are some obvious points, why your structures cannot be correct. For HCOOH (methanoic acid): There are 4 bond pairs of electrons around C and no lone pairs. Formic acid sodium salt. Molecule # of valence e-Lewis Structure NO 3-5 + 3(6) + 1 = 24e- The Valence Shell Electron Pair Repulsion Theory (VSEPR) states the electron pairs surrounding an atom tend to repel each other and the shape of the molecule is the result of this electron pair repulsion. Back. Look at the Lewis structure. They follow the duet rule (2 electrons). It's a very important group. From-http://en.wikipedia.org/wiki/Formate- is the ion CHOO− or HCOO− (formic acid minus one hydrogen ion). 6. For example, if you try to formulate a Lewis structure based on the sum formula C X .
