1. An instructor gave you direction to construct a model of CH3CH2Br molecule by following the Experimental Procedure section of your experiment. First you will need to find the number of valence electrons in CH3CH2Br. The number of valence electrons in an atom of an element is said to be equal to the last digit in the group number of that element in the Periodic Table. Thus, what Groups are C, H, and Br in? 2.An instructor gave you direction to construct a model of CH3CH2Br molecule by following the Experimental Procedure section of your experiment.
