The electronegativity of the following elements increases in the order

Options

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

Answer

C

Explanation

Since electronegativities increases across a period, therefore electronegativity of N is more than that C and electronegativity of P is more that than of Si. Further since electronegativity decreases down a group therefore electronegativity of C is more than that of Si and electronegativity of N is more than that of P. combining the two results the electronegativities of C, Si, P and N increases in the order : `Si lt P lt C lt N` i.e., option ( c) is correct.
