glycosyl halide compound 2 (79% yield in two steps). Desilylating and activating with TBAF turned compound 4 into a thiol nucleophile and thus replaced the anomeric bromide of compound 2 through an SN 2 reaction. Purification by silica column chromatography gave the resulting compound 5 in 54% yield. After removing the acetyl …

Any molecule - indeed any object - has a mirror image. Some molecules are superimposable on their mirror images, that is, all atoms and bonds in a molecule can be simultaneously aligned with identical atoms and bonds in its mirror image. When this is the case, the molecule and its mirror image are identical. Example: C H

multicenter bonding is likely involved. The example you saw in class was for the [FHF]-anion. The Lewis structure has two bonds, but hydrogen only has the 1s orbital available for bonding. The result is a 3-center-4-electron bond (3c4e). This bonding scheme is also present in the hypervalent molecule XeF 2.
