Question

The electron gain
enthalpy with negative
sign is less for oxygen
than that for sulphur.
Why?​

Answer 1

Explanation:

• an atom cannot expand its covalent see beyond for due to absence of Vasant D orbital where as P atom possessive was sent the orbital as a result (Ch 3 )3p equals to zero exist back( Ch 3)3 n equals to does not exist
• due to the small size and compact nature of the oxygen atom the incoming electron is not accommodate with easy as result oxygen has less electron gain enthalpy file with a negative sign that sulphur
• greater the number of elements hydrogen c-h bond present in compound greater is the reduction nature of the compound h 3 PO 2 has two P H Bonds while h3po 2 ph Bond.thus h3po2 is a stronger reduction agent that h3po3
