We have to explain monochlorination.
Monochlorination is the process to introduce one chlorine atom in any organic compound.
Generally, monochlorination takes place by replacement of proton from organic compound. To do chlorination, Cl₂ or HCl is used as reagent.
Inntroduction of one Cl-atom in any organic molecule takes place through free radical mechanism.
The monochlorination of benzene is shown here:

i)
1 is Argon
2 is Kalium
3 is Calcium
ii)
Y belongs to alkaline metals
Z belongs to alkaline earth metals
iii)
Kalium (Y) is alkaline metal

Answer:
0.19 g
Explanation:
Step 1: Given data
Volume of hydrogen at standard temperature and pressure (STP): 2.1 L
Step 2: Calculate the moles corresponding to 2.1 L of hydrogen at STP
At STP (273.15 K and 1 atm), 1 mole of hydrogen has a volume of 22.4 L if we treat it as an ideal gas.
2.1 L × 1 mol/22.4 L = 0.094 mol
Step 3: Calculate the mass corresponding to 0.094 moles of hydrogen
The molar mass of hydrogen is 2.02 g/mol.
0.094 mol × 2.02 g/mol = 0.19 g
