Required information Consider the following zero-one matrix $\begin{bmatrix} 1 & 1 & 1 \\ 0 & 1 & 1 \\ 1 & 1 & 1 \end{bmatrix}$ representing a relation on the ordered set $\{a, b, c\}$. Identify the true statement about the symmetric property of the relation in the given matrix. Multiple Choice The $(1, 2)^{th}$ element is not equal to the $(2, 1)^{th}$ element. So, the relation is symmetric. The $(1, 2)^{th}$ element is equal to the $(2, 1)^{th}$ element. So, the relation is not symmetric. The relation is symmetric because all the diagonal elements are 0s. The $(1, 2)^{th}$ element is not equal to the $(2, 1)^{th}$ element. So, the relation is not symmetric.

The reaction of trans-cinnamic acid with excess bromine is shown in the image. COOH Br? Acetic acid Br COOH of Br 2,3-dibromo- 3-phenylpropanoic acid trans-cinnamic acid Select the reason why the reaction is performed under reflux at 50 °C, rather than at room temperature (20 °C). The temperature must be raised to 50 °C to ensure that bromine is in the liquid phase. Using a temperature of 50 °C prevents the trans-cinnamic acid from isomerizing to the cis form. Raising the temperature to 50 °C prevents the glacial acetic acid solvent from solidifying. The reaction proceeds more quickly at 50 °C than at 20 °C.
