Answer 1

What is the Lewis back? le) Sitha (d) H₂S a CHA (1) WHA 6 H₂O (6) PH3 van donate its Leneis base is electron pair species which easily. PH3. Leuces base The strane strongest among The strongest base will be chą but it does not is just The order of basicity of opposite / reverse of have lone pair. So, it can't act as an lences barse. the given species previous question dhe

SH is the conjugate back on kiggere atom is key "OH Then second most acidic will be because on the basis of Oxygen in the atom among negative charge stable. Skly i orden Whey Hasy Haly PH₂> Sittayella stable dhan H2o , electro-negature all and on oxygen i will be

و؟ F", Bre? A which can is Species as we mone atonic sige of the orbital 9 et , Bronsted-lowrey accepta a A strong et bare proton very easily from Fºto B 1. increaces. A negative charge is diffused in larger Orbital. That in why it is difficult to peotonate the biggue size halide is donating capacity of biggerion decuases and ba basicity decreases alecreasing order of Bosicity in F-yay Brey
