Document Summary

Dec: unbranched alkyl group: number of c prefix with -yl at the end (i. e. methyl me-, ethyl. If both alkyl and halo substituent on chain, number from nearer end regardless of type of substituent. In functional class nomenclature, haloalkanes named as alkyl halides: ethyl chloride, isopropyl bromide, tert-butyl bromide, isobutyl chloride, Indicate position hydroxyl by using number as locant: common names like methyl alcohol, ethyl alcohol, isopropyl alcohol --just normal chain with oh at one end, glycols: alcohols with two hydroxyl groups, named as diols (1,2-ethanediol or. Butene, 2-hexene: indicate location substituent groups by numbers of c to which attached, number substituted cycloalkenes in way that gives c atoms of double bond positions. Increasing boiling points with increase in molecular weight: lowered by branching alkane chain --dispersion forces, reduction of surface area (less. Melting points: not same smooth increase as with boiling points; alternation as go from unbranched alkane with even number c to next one with odd number c.
