Document Summary

Chem 261 introductory organic chemistry i (adapted from prof. c. cairo"s notes) Suggested text problems: all questions in chapter 3. Summary of functional groups: carbon-carbon single bonds, carbon-carbon multiple bonds, carbon single bonded to an electronegative atom. 1: carbon double bonded to oxygen, carbon triple bonded to nitrogen. Alkyl groups: removal of hydrogen from an alkane gives an alkyl group, any alkane can be converted to an alkyl group by removal of a hydrogen. R groups: r is a generic description used to designate any alkyl group. Further classification of functional groups based on degree of substitution: carbons can be classified by the number of other attached alkyl groups, these designations can be used to further classify other functional groups. Alkyl halides, alcohols and thiols. oxygen, halogen or sulfur: primary, secondary, tertiary names refer to the number of groups attached to the carbon bonded to the, amines, amides:
