Concept explainers
(a)
Interpretation:
The observation that occurs when 50 mL of 1-bromobutane (density = 1.27 g/mL) is added to the 100 mL of water should be stated.
Concept Introduction:
Density is defined as the mass per unit volume. It is expressed in g/mL. The compound having low density than water floats on the water and the compound with high density than water sinks in it.
(b)
Interpretation:
The observation that occurs when 50 mL of ethanol (density = 0.79 g/mL) is added to the 100 mL of water should be stated.
Concept Introduction:
Density is defined as the mass per unit volume. It is expressed in g/mL. The compound having low density than water floats on the water and the compound with high density than water sinks in it.
(c)
Interpretation:
The observation that occurs when 50 mL of 1-decanol (density = 0.83 g/mL) is added to the 100 mL of water should be stated.
Concept Introduction:
Density is defined as the mass per unit volume. It is expressed in g/mL. The compound having low density than water floats on the water and the compound with high density than water sinks in it.

She wants to hang out with her co-workers at happy hour in a local club. She is anxious but goes out with them and orders a soda. She feels good that she was able to go out and not have an alcoholic drink. The following week the same scenario plays out without her having an alcoholic beverage. Is she on the path to staying sober or on the road to relapse? Why?arrow_forward
- 1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH,CH2OH (I) → CH3 CH2CH2CH2Br (1) If 13.55 mL of 1-butanol produced 13.23 g of 1-bromobutane, the percentage yield of the product equals: (Assume the density of 1-butanol is 0.81 g/mL, the molar mass of 1-butanol is 74 g/mol, and the molar mass of 1-bromobutane is 137 g/mol.) %arrow_forward2) Complete the reaction: NO.
