Answer is (1) - N

<em>Explanation:</em>

I think the given chart is electronegativity chart.

Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is high, then the attraction to the electrons is high unless the attraction to the electrons is low. </u>

Electronegativity increases from left to right of the periodic table and decreases from up to down. 
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).

The electronegativity values for given atoms are
  N - 3.0
  Na - 0.9
  P - 2.1
  Pt - 2.2 </span>

\boxed{\left( 1 \right){\text{ N}}} will have the strongest attraction for electrons in a chemical bond.

Further Explanation:

Electronegativity

It is the property of an element due to which the shared pair of electrons is attracted towards itself in a chemical bond. More the electronegativity of the element, stronger will be the attraction for electrons and vice-versa. Halogens are highly electronegative in nature as they just one more electron to complete their octet so they have extremely high tendency for electron acceptance.

Periodic trends:

Along a period, electronegativity increase from left to right as number of protons are increasing with the increase in atomic number of the succeeding members.

Down the group, electronegativity decreases from top to bottom as the outermost electrons are situated far apart from the atomic nucleus due to increasing size of the succeeding members.

The electronegativity of N is 3.0.

The electronegativity of P is 2.1.

The electronegativity of Na is 0.9.

The electronegativity of Pt is 2.2.

Nitrogen has the highest electronegativity value among the given elements so it has the strongest attractions for electrons in a chemical bond. Therefore option (1) is the correct answer.

1. a. FeS + 2HCl --> FeCl2 + H2S
    b. This is a double- replacement reaction. (The elements "switch partners".)

2. a.2Na + F2 --> 2NaF
    b. This is a composition/synthesis reaction. (The two reactants are combining or synthesizing to make one product.)

3. a. 2HgO --> 2Hg + O2
    b. This is a decomposition reaction. (The single reactant is breaking down or "decomposing" into multiple reactants.)

4. Hydrogen gas reacts with oxygen gas to create water in a composition/synthesis reaction.

I hope these answers will help you! If you need any explanation, ask and hopefully I can get back to you. ;)

Given that Δ H ∘ f [ Br ( g ) ] = 111.9 kJ ⋅ mol − 1 Δ H ∘ f [ C ( g ) ] = 716.7 kJ ⋅ mol − 1 Δ H ∘ f [ CBr 4 ( g ) ] = 29.4 kJ
JulsSmile [24]

Answer:

283.725 kJ ⋅ mol − 1

Explanation:

C(s) + 2Br2(g) ⇒ CBr4(g) , Δ H ∘ = 29.4 kJ ⋅ mol − 1

\frac{1}{2}Br2(g) ⇒ Br(g) ,  Δ H ∘ = 111.9 kJ ⋅ mol − 1

C(s) ⇒ C(g) ,  Δ H ∘ = 716.7 kJ ⋅ mol − 1

4*eqn(2) + eqn(3) ⇒ 2Br2(g) + C(s) ⇒ 4 Br(g) + C(g) , Δ H ∘ = 1164.3 kJ ⋅ mol − 1

eqn(1) - eqn(4) ⇒ 4 Br(g) + C(g) ⇒ CBr4(g) , Δ H ∘ = -1134.9 kJ ⋅ mol − 1

so,

   average bond enthalpy is \frac{1134.9}{4} = 283.725 kJ ⋅ mol − 1
