MCQ
The electronegativity of the following elements increases in the order
  • A
    $C, N, Si, P$
  • B
    $N, Si, C, P$
  • ✓
    $Si, P, C, N$
  • D
    $P, Si, N, C$
✓

Answer

Correct option: C.
$Si, P, C, N$
c
The electronegativities of $C , N , Si$ and $P$ are in the order of.

$Si \,<\, P\, <\, C\, < \,N$

In a period, electronegativity increases from left to right. In a group, the electronegativity decreases down the group.
