Consider the following sequence of reaction:

If electronic configuration of element X is `[Ne]3s^(1)`, then which of the following order is correct regarding given enthalpies?

Options

A. `|DeltaH_(4)|=|DeltaH_(5)|`
B. `|DeltaH_(2)|gt|DeltaH_(1)|`
C. `|DeltaH_(2)|gt|DeltaH_(3)|`
D. `|DeltaH_(1)|=|DeltaH_(6)|`

Answer

A, B, D

Explanation

(a) `|DeltaH_(4)|=|DeltaH_(5)|[(DeltaH_(eg))_(X)=(DeltaH_(IE))_(X^(-))]`
(b), (c)`toDeltaH_(3) gt DeltaH_(2) gtDeltaH_(1)` [Successive IE always higher than previous IE]
(c) `|DeltaH_(1)|=|DeltaH_(6)|[(DeltaH_(IE))_(X)=(DeltaH_(eg))_(X^(-))]`
