The electronegativity of the given elements increases in the order

Options

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

Correct answer

C.   Si , P , C , N

Step-by-step solution

Since electronegativities increase in a period from left to right, therefore, electronegativity of N is more than that C and electronegativity of P is more than that of Si . Further since electronegativities decrease down a group in the periodic table, therefore, electronegativity of C is more than that of Si and electronegativity of N is more than that of P . Hence, the electronegativity of the given elements increases in the order   Si , P , C , N .
