Aldehydes are named by replacing the terminal –e of the corresponding alkane name with –al. The longest chain selected as the base name must contain the –CHO group, and the –CHO carbon is always numbered as carbon 1

Conjugated unsaturated systems have a p orbital on a carbon adjacent to a double bond The p orbital can come from another double or triple bond The p orbital may be the empty p orbital of a carbocation or a p orbital with a single electron in it (a radical)

Introduction. The problems in this chapter examine some variations on the apartment market described in the text. In most of the problems we work with the true demand curve constructed from the reservation prices of the consumers rather than the “smoothed” demand curve that we used in the text

Bell Labs, Lucent Technologies, Crawford Hill Lab, Holmdel, NJ 07733, USA: herwig@lucent.com Abstract Optical communication has advanced into the tera-era deploying 1/2 terameter of fiber and carrying several Tb/s per fiber. Remaining challenges include extending the success of point-to-point long-haul to metropolitan networks and broadband access applications. Introduction Reflecting on the past 15 years of optical communication, one can only marvel at the amazing advances in this technology and in its applications
