rganometallic compounds are compounds that have a carbon-metal bond; they lie at the place where organic and inorganic chemistry meet. You are already familiar with at least one organometallic compound, sodium acetylide (NaC=CH), which has an ionic bond between carbon and sodium. But just because a compound contains both a metal and carbon isn't enough to classify it as organometal-

itrogen-containing compounds are essential to life. Their ultimate source is atmo- spheric nitrogen which, by a process known as nitroge. nitrogen fixation, is reduce ced to ammonia, then converted to organic nitrogen compounds. This chapter describes the chemistry of amines, organic derivatives of ammonia. Alkylamines have their nitro- gen attached to sp'-hybridized carbon; arylamines have their nitrogen attached to an sp2-hybridized carbon of a benzene or benzene-like ring

ou have already had considerable experience with carbanionic compounds and rgani their applications in synthetic organic chemistry. The first was acetylide ion in Chapter 9, followed in Chapter 14 by organometallic compounds-Grignard reagents, for example-that act as sources of negatively polarized carbon. In Chapter 18 you learned that enolate ions-reactive

he value of alkyl halides as starting materials for the preparation of variety of organic functional groups has been stressed many times. In our earlier discussions, we noted that aryl halides are normally much less reactive than alkyl halides in reactions that involve carbon-halogen bond cleavage. In the present chapter you will see that aryl halides can exhibit their own patterns of chemical reactivity, and that these reac

4.1 There are four C. H, alkyl groups, and so there are four C. H, CI alkyl chlorides. Each may be named by both the functional class and substitutive methods. The functional class name uses the name of the alkyl group followed by the halide as a second word. The substitutive name modifies the name of the corresponding alkane to show the location of the halogen atom

10.1 As noted in the sample solution to part(a), a pair of electrons is moved from the double bond toward the positively charged carbon

SOLUTIONS TO TEXT PROBLEMS 13.1 The field strength of an NMR spectrometer magnet and the frequency of electromagnetic radia he Ire tion used to observe an NMR spectrum are directly proportional. Thus, the ratio 4.7 T/200 MHz is the same as 1.41/60 MHz. The magnetic field strength of a 60-MHz NMR spectrometer is

Oxirane 2-(Chloromethyl)oxirane This compound is more commonly known as epichlorohydrin. (c)Epoxides may be named by adding the prefix epoxy to the IUPAC name of a parent compound specifying by number both atoms to which the oxygen is attached

22.2 N,N-Dimethylcycloheptylamine may also be named as a dimethyl derivative of cycloheptanamine. -N(CH3)2 N,N-Dimethylcycloheptanamine 22.3 Three substituents are attached to the nitrogen atom; the amine is tertiary. In alphabetical order, the s substituents present on the aniline nucleus are ethyl, isopropyl, and methyl. Their positions are

The writing of clinical record A patient's health record plays many important roles: It provides a view of the patient's health history/status It serves as the legal document describing the healthcare services provided to the patient It provides a method for clinical communication and care
