An element has electronegativity on Mulliken Scale is 2.8 than what is the electronegativity of element on All - Red Roschow Scale

Options

A. `0.156`
B. `0.256`
C. `5.6`
D. `0.286`

Answer

B

Explanation

`X_(m) = 2.8 X_(P) " " X_(P) = (2.8)/(2.8) = 1`
`X_(P) = 0.744 + X_(AR)`
`1 = 0.744 + X_(AR)`
`X_(AR) = 1 - 0.744 = 0.256`
