The Lewis structure of azide molecule and the bond angle of N-N-N have to be written. Concept Introduction: Lewis Structure: A Lewis structure shows a covalent bond as pair of electrons shared between two atoms. Procedure to write Lewis formulas: 1) The symbols of the atoms that are bonded together in the molecule next to one another are arranged. 2) The total number of valence electrons in the molecule is calculated by adding the number of valence electrons for all the atoms in the molecules. If the species is an ion, then the charge of ion into account by adding electrons, if it is a negative ion or subtracting electrons if it is a positive ion. 3) A two-electron covalent bond is represented by placing a line between the atoms, which are assumed to be bonded to each other. 4) The remaining valence electrons as lone pairs about each atom are arranged so that the octet rule is satisfied for each other.

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
