We use mild oxidising agent( like pcc)

For Oxidation of primary alcohol to aldehyde if we use Strong oxidising agent like KMnO4etc then primary alcohol to Carboxylic acid but for aldehyde we should use mild oxidising agent ( like pcc)

Which type of compounds prefer to become carboxylic acid in cannizaro reaction? Electron donating aromatic compounds or electron withdrawing aromatic compounds?

Electron withdrawing aromatic compounds, as they have increased reactivity of carbonyl group, which undergoes oxidation more easily.

Isopropyl alcohol,CH3CHOHCH3, is used in rubbing alcohol mixtures. How much heat is absorbed by alcohol if 10.0grams evaporates. The heat of vaporation is 42.1 kJ/mol

n(CH3CHOHCH3) = m(CH3CHOHCH3)/m(CH3CHOHCH3) = 10.0g/60g/mol = 0.1667mol.Q = L(CH3CHOHCH3) * n(CH3CHOHCH3) = 42.1 kJ/mol * 0.1667mol = 7.02kJ.

the vapor pressures of pure propyl alcohol and isopropyl alcohol are 21.0 mmHg and 45.2 mmHg. respectively, above a solution in which the mole fraction of isopropyl alcohol is 0.750

Pressure is directly proportional to MoleTherefore,P = knk= P/nP1/n1 = P2/n221.0 mmHg / x = 45.2 mmHg/0.750x = (21.0 mmHg * 0.750) / 45.2 mmHgx= 0.35 (pure propyl alcohol  mole ratio)
