Then, predict methanol 4t using the calculated at of ethanol (Is it cor > ethanol At?). To predict the At of 1-butanol, use the At of
a) Predict the at trend as the molecular mass of alcohols decreases. b) Predict the At trend of 1-Butanol, 2-Butanone and bertane and arranged in increasing order (use the inequality sign "<").
C) For alcohols only, create a graph of molar mass versus calculated at. Describe the at trend of alcohol molar mass plotted against its at (Show the graph below.):
TABLE 2 CHANGE INFLUENCE OF INTERMOLECULAR FORCES ON TEMPERATURE Volatile Liquid Calculated At (°C) Intermolecular Forces Explanation for Calculated at 1-butanol 2- butanone Hentane ***Note: Explain based on the 4t (°C) profile and strength of intermolecular forces. DATA ANALYSIS d) Arrange the abovementioned compounds according to increasing At (from left to right). Briefly explain the trend by identifying two primary factors or reasons for the order. e) What does At represent? What does high At mean?
