WebSome hydrocarbons have one or more carbon–carbon double bonds (denoted C=C). These hydrocarbons are called alkenes (see section 3.2. for more information) Note that the names of alkenes have the same stem as the alkane with the same number of carbon atoms in its chain but have the ending –ene.Thus, ethene is an alkene with two carbon atoms per … WebFeb 23, 1977 · Principles of Organic Chemistry [Murray, Peter R.S.] on Amazon.com. *FREE* shipping on qualifying offers.

Question 1 Which of the following statements is wrong? a) UV absorption is attributable to electronic transitions. b) UV spectra provide information about valence electrons. WebThe best approach for spectroscopy problems is the following steps: Calculate the degree of unsaturation to limit the number of possible structures. Remember, each degree of unsaturation is a ring or pi bond (likely an alkene or carbonyl). An alkyne has two degrees of unsaturation (2 pi bonds), and an aromatic ring has four (3 pi bonds plus a ...
