Give the major product formed when phenol is heated with concentrated H2SO4 and SO3. (There is more than one correct answer, but
iris [78.8K]

Answer:

See image attached and explanation

Explanation:

The reaction of phenol with SO3/H2SO4 is an electrophilic reaction. The electrophile attacks portions of high electron density in the substrate phenol.

The -OH group activates phenol towards electrophilic substitution at the ortho and para positions, hence the product(s) formed in this reaction(only one product is shown here as required by the question).

The sulphonation of phenol using concentrated sulfuric acid at lower temperature yields majorly the ortho product whereas at higher temperature the para product predominates.

Why is a liquid able to flow
luda_lava [24]
Since the particles can move, the liquid<span> can flow</span> <span>and take the shape of its container. Some insects, such as pond-skaters, are able</span><span> to walk on water without sinking. This is because the forces of attraction between the water particles pull the particles at the surface together.</span>

what is a molarity of a solution in 9.8 moles of sodium chloride NaCL is dissolved in water to a final volume 3.2 l
Anika [276]
Answer:
molarity = 3.0625 M

Explanation:
Molarity can be calculated using the following rule:
molarity = number of moles of solute / volume of solution

We are given that:
number of moles of solute = 9.8 moles
volume of solution = 3.2 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = 9.8 / 3.2
molarity = 3.0625 M

Hope this helps :)
