This attack pushes electrons from the carbon-oxygen bond to the oxygen atom, allowing the R group to bond. In the second step, the newly acquired lone pair ... On the left, we see an O with 2 single bonds and 2 lone pair electrons. Treating the lone pairs as single bonds, we assign the O an sp3 orbital and the distance between each electron pair and each bond will be 109.5 degrees. On the right, the O has a double bond, but still has its 2 electron pairs. We would therefore assign this oxygen an sp2 ...

Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions. Figure 4 shows an example of two molecules, chiral ...
