Arrange the following elements in increasing order of...

Arrange the following elements in increasing order of electronegativity: N,O,F,C,Si\mathrm{N}, \mathrm{O}, \mathrm{F}, \mathrm{C}, \mathrm{Si} Choose the correct answer from the options given below:

Options

  1. ASi <\lt C <\lt O <N<F\lt \mathrm{N} \lt \mathrm{F}
  2. BO<F<N<C<Si\mathrm{O} \lt \mathrm{F} \lt \mathrm{N} \lt \mathrm{C} \lt \mathrm{Si}
  3. CF<O<N<C<\mathrm{F} \lt \mathrm{O} \lt \mathrm{N} \lt \mathrm{C} \lt Si
  4. DSi <\lt C <\lt N <\lt O <\lt F

Correct answer

D. Si <\lt C <\lt N <\lt O <\lt F

Step-by-step solution

Electronegativity increases across the period on moving left to right. It decreases on moving down the group. The correct option is Si<C<N<O<F\mathrm{Si} \lt \mathrm{C} \lt \mathrm{N} \lt \mathrm{O} \lt \mathrm{F}
