We have to round off each measurement to the number of significant figures.
The correct answers are: 265.9, 0.00045 and 65 respectively.
265.991 when expressed in 4 significant figure it rounds off as 265.9 because 265.9 represents the value 265.991.
0.0004513 when expressed in 2 significant figure it rounds off as 0.00045 because zero before and after decimal are not significant.
6593 when expressed in 2 significant figure it rounds off as 65.
The answer would be : AlCl3.
Hope this helps !

<span>1, 3 butadiene. The Diels-Alder reaction is a conjugate addition reaction of a conjugated diene to an alkene (the dienophile) to produce a cyclohexene. The simplest diene is 1,3-butadiene. It can be viewed as the union of two vinyl groups. It would react with an alkene substitutient ethene to form cyclohexene which leads to the conversion of 2 Ď€-bonds into 2 new stronger Ď-bonds.</span>
