1-Butanol, 1-butene, and di-n-butyl ether are all removed from the product by washing with concentrated sulfuric acid. Explain w

Alecsey [184]

Answer:

1-bromobutane, unlike others, will not be removed because it is an alkane and inert to concentrated sulfuric acid.

Explanation:

Alkanes are saturated organic compounds, primarily made up of hydrogen and carbon atoms. Saturation implies that they posses no double or triple bonds, therefore making them stable and unresponsive to addition reactions and also, concentrated sulfuric acid.

1-Butanol is a primary alcohol. Primary alcohols will react with acids to produce alkyl halides. 1-butene, as an alkene, will react with concentrated sulfuric acid to produce alkyl hyrgensulfate, while di-n-butyl will produce an ether when it reacts with concentrated sulfuric acid.

Therefore, these organic compounds will be washed and converted to other compounds by concentrated sulfuric acid except 1-bromobutane.

A small bubble rises from the bottom of a lake where the temperature and pressure are 4.0 C and 3.0 atm, to the water’s surface,

Varvara68 [4.7K]

Answer:

The final volume of the bubble is 7.13 mL.

Explanation:

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 3 atm

$P_2$ = final pressure of gas = 0.95 atm

$V_1$ = initial volume of gas = $2.1 mL=0.0021 L$

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $4^oC=273.15+4K=277.15 K$

$T_2$ = final temperature of gas = $25^oC=273.15+25 k=298 .15 K$

Now put all the given values in the above equation, we get:

$\frac{3 atm\times 0.0021 L}{277.15 K}=\frac{0.95 atm\times V_2}{298.15 K}$

$V_2=\frac{3 atm\times 0.0021 L\times 298.15 K}{277.15 K\times 0.95 atm}=0.00713 L = 7.13 mL$

The final volume of the bubble is 7.13 mL.

Describe how functional groups affect an organic molecule's' chemical reactivity

vazorg [7]

Functional groups are set of commonly found groups of atoms covalently bonded to carbon in organic molecules.The unique functional groups present on a bio molecule determine reactivity solubility and other physical properties that lead to its biological role in living organisms.

A chemist measures the thermometer in the calorimeter and notices the temperature has increased. What does this mean about the r

Readme [11.4K]

Answer: As the temperature of the thermometer has increased it shows that that the reaction that has taken place was exothermic. In exothermic reactions heat is given out and temperature of the surroundings increases which is indicated by the increase in temperature of the thermometer.
