5. When ortho-bromonitrobenzene is treated with NaOH at elevated temperature, only one product is formed. (a) Draw the product.
Mice21 [21]

Answer:

The product formed is orthonitrophenol

Explanation:

The compound orthonitrophenol is formed when ortho-bromonitrobenzene is treated with NaOH at elevated temperature.

The reaction leads to the formation of an intermediate stabilized by resonance. This intermediate can not be formed by the meta isomer because a resonance stabilized intermediate can not be formed and the product is not stabilized by intramolecular hydrogen bonding hence this reaction will not occur.

how many moles of gas does it take to occupy 120 liters at a pressure of 2.3 atmospheres and a temperature of 340 K?
dezoksy [38]
Data:

P (pressure) = 2.3 atm
V (volume) = 120 L
T (temperature) = 340 K
n (number of mols) = ?
R (Gas constant) = 0.082 (atm*L/mol*K)

Formula: 

p*V = n*R*T

Solving:
p*V = n*R*T
2.3*120 = n*0.082*340
276 = 27.88n
27.88n = 276
n = \frac{276}{27.88}
n = 9.89956...\to \boxed{\boxed{n\approx 9.90\:mols}}\end{array}}\qquad\quad\checkmark
