Answer 1

a.) Benzoic acid :- It is not a solvent. It is colourless crystalline solid aromatic compound. Its molar mass is 122.123 gram per mol. Its melting point is 122 °C. It is used as food preservatives. It occurs naturally in plants.

b.) Ethyl 4-aminobenzoate :- It is not a solvent. It is also know as benzocaine. Its molar mass is 165.19 gram per mol. Its melting point isi 88-90 °C. It is synthesized by esterification from ethanol and p-aminobenzoic acid. Its use in pharmaceutical industry as a pain reliever.

c.) 9-fluorenone :- It is not a solvent. It is an aromatic organic compound. It is bright fluorescent yellow in colour and solid at room temperature. Its melting point is 84 °C. Its molar mass is 180.206 gram per mole. It is used to make antimalarial drug.

d.) HCl :- It is not a solvent. It is highly polar protic inorganic compoud. It is acidic in nature. At room temperature it is colourless gas, which forms white fumes upon contact with atmospheric water. Its molar mass is 36.46 gram per mol. Its odor is pungent. Its melting point is -114.22 °C and boiling point is -85.05 °C.

e.) Diethyl ether :- It is common laboratory organic solvent. It is non-polar solvent and used in liquid-liquid extraction. When it is used with aquous solution, its layer on the top because it has lower density than water. Its odor is sweet. Its molar mass is 74.123 gram per mol. It is liquid at room temperature and its boiling point is 34.6 °C.

f.) NaCl :- It is not a solvent. It is know as table salt, rock salt or table salt, we use in daily life. It is an ionic compoud and white solid. Its melting point is 1465 °C. Its molar mass is 58.443 gram per mol.

g.) Anhydrous sodium sulfate :- It is not a solvent. It is white crystalline solid at room temperature. Its molar mass is 142.04 gram per mol. Its melting point is 884 °C.

h.) NaOH :- It is not a solvent. It is colourless crystalline solid. Its melting point is 318 °C. Its molar mass is 39.9971 gram per mol. Its also known as caustic soda. It is highly basic in nature.
