Multiple Choice Options

  • A C>P>At>Br\mathrm{C}>\mathrm{P}>\mathrm{At}>\mathrm{Br}
  • B Br>C>At>P\mathrm{Br}>\mathrm{C}>\mathrm{At}>\mathrm{P}
  • C Br>P>At>C\mathrm{Br}>\mathrm{P}>\mathrm{At}>\mathrm{C}
  • D P>Br>C>At\mathrm{P}>\mathrm{Br}>\mathrm{C}>\mathrm{At}

Step-by-Step Verified Solution

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as we move from left to right across a period due to increase in effective nuclear charge.

Here are the Pauling electronegativities for the elements:

  • Carbon (C): 2.55

  • Phosphorus (P): 2.19

  • Astatine (At): 2.2

  • Bromine (Br): 2.96

Based on these values, the correct order of electronegativity from highest to lowest is Br > C > At > P.

Therefore, Option B is the correct answer:

Br > C > At > P
