The answer is (1) 24. There are 26 protons in nucleus of Fe atom. There is 26 electrons in Fe atom. Fe atom loses 2 electrons and change to Fe2+ ion. So there is 24 electrons in Fe2+ ion.

Atomic number of iron = 26 
<span>Number of protons in the neucleus = 26 </span>
<span>Number of electrons in a neutral Fe atom = 26 </span>
<span>Number of electrons in Fe2+ ion = 26 - 2 = 24</span>

Free radical Brormination is a slower reaction than chlorination but it is a synthetic route often used to make alky bromides. A
mariarad [96]

Answer and explanation:

The relative rates of free radical halogenation is in the order of,

F₂ (10⁸) > Cl₂ (1) > Br₂ (10⁻¹¹) > I₂ (10⁻²²)

The above order also show a decreasing reactivity from left to right

Hence, reaction of fluorine with alkanes is highly reactive and it is too difficult to control.

The reaction with Cl₂ is moderately fast, while with Br₂ is slow and with I₂ is too slow reaches to equilibrium.

Hence in general we don't prefer radical fluorination of alkanes.
