The materials in the order of increase in their conductivity should be arranged. Concept introduction: According to band theory, solids are classified as conductors, semiconductors, and insulators. As per band theory, bands are a continuum of energy levels. The bands are of two types: valence band and conduction band. The band that holds valence electrons is valence band and band that is slightly higher in energy than valence band is conduction band. On the basis of band theory, partly filled band shows conduction and are called conductors, and fully filled band doesn’t show conduction and are insulators.

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.
