Strong reducing behaviour of H3PO2 is due to :
Presence of one - OH group and two P - H bonds
High electron gain enthalpy of phosphorus
High oxidation state of phosphorus
Presence of two - OH groups and one P - H bond
As we discussed in the concept
Hypophosphorus Acid -
H3PO2 (+1), monobasic
- wherein
strong reducing behaviour of H3PO2 is due to presence of one -OH group and two P-H bonds
Option 1)
Presence of one - OH group and two P - H bonds
This option is correct
Option 2)
High electron gain enthalpy of phosphorus
This option is incorrect
Option 3)
High oxidation state of phosphorus
This option is incorrect
Option 4)
Presence of two - OH groups and one P - H bond
This option is incorrect
