Which of the following molecules would have the highest boiling point? CH3CH2OkH снзоснз CHCI 3FH2 CH3CH2CH3 CH3CH2l
Question 12 Which of the following statements is false about CH3CH2CH3 and CH3CH2OH? Your answer: O Hydrogen bonding is the only type of intermolecular forces between CH3CH2OH molecules. O (C) atom makes sp hybridization in CH3CH2CH3 molecule. o Only dispersion forces exist between CH3CH2CH3 molecules. OCH3CH2OH has stronger intermolecular forces than CH3CH2CH3. O CH3CH2CH3 molecule has tetrahedral geometry. Clear answer Back Next
The heats of combustion of ethane (C2H6) and butane (C4H10) are 52 kJ/g and 49 kJ/g, respectively. We need to produce 1.000 x 103 kJ heat by burning one of the fuels. Which fuel will emit the least amount of CO2? 1. Calculate the number of grams needed of each fuel: 2. Calculate the number of moles of each fuel: 3. Write down the balanced chemical equation for the combustion of the fuels: 4. Calculate the number of moles of...
