Electronegativity of the following elements increases in the order

Options

  1. AC , N , Si , P
  2. BN, Si, C, P
  3. CSi, P, C, N
  4. DP, Si, N, C

Correct answer

C. Si, P, C, N

Step-by-step solution

As electronegativity increases across the period, therefore, electronegativity of nitrogen ( N ) is more than carbon (C) and electronegativity of P is more than Si . Also electronegativity decreases down the group, therefore electronegativity of carbon is more than Si and electronegativity of N is more than P . Hence, the correct increasing order will be Si, P, C, N.
