The electronegativities of N, C, Si and P are in the order

Options

A. `P lt Si lt C lt N`
B. `Si lt P lt N lt C`
C. `Si lt P lt C lt N`
D. `P lt Si lt N lt C`

Answer

C

Explanation

Electronegativity increases on moving left to right in a period and decreases for the period below it (`because`n= increases)
`because`(N and C) and (Si and P) respectively belong to (n=2) and (n=3).
`therefore` Electronegativity of `N gt` electronegativity of C and electronegativity of `P gt` electronegativity of Si Hence, correct order is: `Si lt P lt C lt N`
