Document Summary
Note: in general an alkanal proton (d) will not couple to adjacent protons (c) and will appear as a singlet. The converse is also true and so c appears as a triplet. Hydrogens in alkenes can show complicated splitting not following the n+1 rule. Alkyl halides are organic molecules containing a halogen atom bonded to an sp3 hybridized carbon. The halogen in halides often denoted symbol atom is atom. by the (cid:862)x(cid:863). Depending on the number of carbons bonded to the carbon with the haloge(cid:374) ato(cid:373), rx"s are classified as: Find the longest chain containing the halogen. Number from the end which gives the halogen the smallest possible value if no other functional group is present. Locate each halogen in the parent chain using the assigned number. Functional groups determine the numbering when present. Use the prefixes fluoro-, chloro-, bromo- and iodo-.
