Carbon 2 belongs to the carboxylic functional group which is attached to the 3 atoms and it also contains no lone pair of electrons. different atoms with respect to each other and the formations of the valence In H2O, a central oxygen atom is surrounded by four separate regions of high electron density. In ethane, the carbon atoms use sp3 hybrid orbitals for the formation of sigma bonds. molecules, it is average, or it is calculated using the molecular mass of the 90 B. If this were the case, the bond angle would be 90, as shown in Figure 5.6, because p orbitals are perpendicular to each other. Out of the fours bonds, the two bonds that lie within the paper plane are shown as ordinary lines, the solid wedge represent a bond that point out of the paper plane, and the dashed wedge represent a bond that point behind the paper plane. this molecule. may be unshared. In this step, we need to complete the octet of outer atoms(hydrogen and oxygen) by putting the remaining valence electron we have. This small difference between the predicted angle and the observed angle can be explained by proposing that the unshared pair of electrons on nitrogen repels the adjacent bonding pairs more strongly than the bonding pairs repel each other. bonds. CH3COOH molecule contains a functional group that is also called the carboxylic group(COOH). It is impossible to have two bonds because you cannot have the orbitals angled the correct way to have a second bond between the same two atoms. Both C-O bonds in acetate are 126 pm which is roughly the average of C=O double bond (123 pm) and the C-O single bond (132 pm) of acetic acid. important factors in determining its properties, especially its activity. use the concept of resonance to explain why carboxylic acids are stronger acids than alcohols. outward so that their ability to overlap is stronger than that of normal Acetic acids CH3, and OH are in a sp3 tetrahedral shape and CO is in a sp2 trigonal planar. group through the nitrogen.
