The <em>Diels-Alder reaction</em> is the <em>conjugate addition of an alkene to a diene</em>, Using 1,3-butadiene as a typical diene, the Diels-Alder reaction may be represented by the general equation following general reaction where polarity occurs and followed by addition.<br />

The alkene that adds to the diene is called the <em>dienophile</em>. Because the Diels-Alder reaction leads to the formation of a ring, it is termed <em>a cycloaddition </em>reaction. <div align="right"> <a href="/chapters/tutorial/chemistry/alkadienes.htm"> more...</a> </div>

<!-- Physics Question/Answer start-->
A thin uniform wire AB of length 1m, an unknown resistance X and a resistance of 12 Ohm are connected by thick conducting strips, as shown in the below figure. A battery and a galvanometer (with a sliding jockey connected to it) are also available. Connections are to be made to measure the unknown resistance X using the principle of Wheatstone bridge. Answer the following questions.<br>

(a) Are there positive and negative terminals on the galvanometer?<br>
(b) Copy the figure in your answer book and show the battery and the galvanometer (with jockey) connected at appropriate points.<br>
(c) After appropriate connections are made, it is found that no deflection takes place in the galvanometer when the sliding jockey touches the wire at a distance of 60cm from A. Obtain the value of the resistance of X.<br>
