P-H bond

what is meant by non ionisable P-Hbonds. howmany non ionisable P-H bonds r there in H3PO3?

bcoz electronegetivity of p=1.8 and of H is 2.1

so, H is del -ve in P-H bond..if H is released, it will be released as H-(hydride ion)...ie h3po3 giving electron(as hydride ion) to other species..hence h3po3 is reductant...😑👍👍👍👍👍

Non-ionisable P-H bonds toh reduction mein kaam aate hain...H cannot be separated as a proton. Instead it is given up as a hydride ion in a concerted mechanism of reduction. Those H's attached to oxygen are very much ionisable due to oxygen's electronegativity. There is one non-ionisable and two ionisable bonds here.

and It was given bond angle of PH3 is greater than that of NH3...i feel due to lonepair bondpair repulsions ....it is the otherway round...pls comment and confirm

Bond angle of NH3 is greater than the bond angle of PH3

i found something shiva in JD lee

that :-
H3PO3 contains 2 acidic H atoms ( the OH groups ), one reducing H ( the P - H Hydrogen atom ) . consequently only two of the three H atoms can ionize, and the acid is dibasic.

H3PO3 is moderately strong reducing agent.
