|Chapter 5: | |Structure and Preparation of Alkenes. | |Elimination Reactions | Summary Alkenes contain the C=C functional group which can be prepared by 1‚2-elimination reactions such as: • dehydration of alcohols (- H2O) or • dehydrohalogenation of alkyl halides (- HX). Zaitsev’s rule indicates that the preferred product is the more highly substituted

13. ORGANIC CHEMISTRY IV) ALKYNES SYNOPSIS Alkynes are commonly known as acetylenes. Acetylene is the simplest and important member of the alkyne series. • Alkynes contain – C ≡ C – • General molecular formula of alkynes is CnH2n–2 • Triple bonded carbons are ‘sp’ hybridized and greater s – character is associated with it. • Alkynes will exhibit chain‚ position and functional isomerism. • Their functional isomers are alkadienes and cyclo alkenes. • The minimum number of carbons required to exhibit

parting question: Was he happy? However‚ he is distracted when he discovers his wife had overdosed on sleeping tablets. When he meets Clarisse again‚ he finds himself behaving differently‚ starting with tasting the rain as Clarisse suggested. The Mechanical Hound is then introduced as it described as alive‚ but not truly. When Montag begins to wonder and question Beatty about the books‚ a report was rung in. The old woman‚ who was reported‚ stands in her house‚ surrounded by books. When the firemen

ALCOHOLS Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. For the purposes of UK A level‚ we will only look at compounds containing one -OH group. For example: Primary alcohols In a primary (1°) alcohol‚ the carbon which carries the -OH group is only attached to one alkyl group Some examples of primary alcohols include: Secondary alcohols In a secondary (2°) alcohol‚ the carbon with the -OH group attached is joined directly to
