Answer:
The carbocation intermediate reacts with a nucleophile to form the addition product.
Explanation:
The reaction of benzene with an electrophile is an electrophillic substitution reaction. Here the electrophile replaces hydrogen. There is no formation of carbocation as intermediate in the reaction. Infact there is transition state where the electorphile attacks on benzene ring and at the same time the hydrogen gets removed from the benzene. So a transition carbocation is formed.
The general mechanism is shown in the figure.
i) Attack of the electrophile on the benzene (which is the nucleophile)
ii) The carbocation intermediate loses a proton from the carbon bonded to the electrophile.
iii) the carbocation formation is the rate determining step.
iv) There is no formation of addition product.
Thus the wrong statement is
The carbocation intermediate reacts with a nucleophile to form the addition product.
N2 + 3 H2 >> 2 NH3
moles NH3 = 11.50 g /17.0307 g/mol=0.6753
the ratio between H2 and NH3 is 3 : 2
moles H2 needed = 0.6753 x 3/2 =1.013
mass H2 = 1.013 mol x 2.106 g/mol=2.042 g
The most appropriate unit to take the weight of a cow would be kilograms.
Meters are a unit of distance and are not applicable here
A gram is too small to use in this instance
Based on the properties of ideal gases, the true statements are:
- They have a small mass.
- They have no volume.
- They have no intermolecular forces.
<h3>What is an ideal gas?</h3>
An ideal gas is a gas which is assumed to have ideal properties.
The properties of an ideal gas are as follows:
- they have negligible mass
- do not attract or repel one another due to negligible intermolecular forces
- take up no space (have no constant volume)
- they collide with one another and the walls of their container
Therefore, based on the properties of ideal gases, the true statements are:
- They have a small mass.
- They have no volume.
- They have no intermolecular forces.
